Abstract
TpPL7A and TpPL7B, members of CAZy family PL7, act as β-glucuronan lyases. TpPL7A diverges by lacking the catalytic histidine, identified as the Brønsted base in PL7 alginate lyases. Our research, including TpPL7A's crystal structure, and mutagenesis studies, reveals a shared syn-β-elimination mechanism with a single tyrosine serving as both base and acid catalyst. This mechanism may extend to subfamily PL7_4 glucuronan lyases.

Int J Biol Macromol 2023; 253:126551. [PMID: 37659488 DOI: 10.1016/j.ijbiomac.2023.126551] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 07/27/2023] [Accepted: 08/12/2023] [Indexed: 09/04/2023]
Abstract
Chondroitin sulfate (CS) is a member of glycosaminoglycans (GAGs) and has critical physiological functions. CS is widely applied in medical and clinical fields. Currently, the supply of CS relies on traditional animal tissue extraction methods. From the perspective of medical applications, the biggest drawback of animal-derived CS is its uncontrollable molecular weight and sulfonated patterns, which are key factors affecting CS activities. The advances of cell-free enzyme catalyzed systems and de novo biosynthesis strategies have paved the way to rationally regulate CS sulfonated pattern and molecular weight. In this review, we first present a general overview of biosynthesized CS and its oligosaccharides. Then, the advances in chondroitin biosynthesis, 3'-phosphoadenosine-5'-phosphosulfate (PAPS) synthesis and regeneration, and CS biosynthesis catalyzed by sulfotransferases are discussed. Moreover, the progress of mining and expression of chondroitin depolymerizing enzymes for preparation of CS oligosaccharides is also summarized. Finally, we analyze and discuss the challenges faced in synthesizing CS and its oligosaccharides using microbial and enzymatic methods. In summary, the biotechnological production of CS and its oligosaccharides is a promising method in addressing the drawbacks associated with animal-derived CS and enabling the production of CS oligosaccharides with defined structures.

Platelet factor 4 (CXCL4/PF4) upregulates matrix metalloproteinase-2 (MMP-2) in gingival fibroblasts. Sci Rep 2022; 12:18636. [PMID: 36329090 PMCID: PMC9633774 DOI: 10.1038/s41598-022-19850-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 09/06/2022] [Indexed: 11/06/2022] Open
Abstract
Periodontitis is a chronic inflammatory disease characterized by the release of matrix metalloproteinases (MMPs) from resident connective tissue cells in tooth-supporting tissues (periodontium). Platelet activation, and the attendant release of pro-inflammatory chemokines such as platelet factor 4 (CXCL4/PF4), are associated with periodontitis although the associated biochemical pathways remain undefined. Here we report that recombinant PF4 is internalized by cultured human gingival fibroblasts (hGFs), resulting in significant (p < 0.05) upregulation in both the production and release of MMP-2 (gelatinase A). This finding was corroborated by elevated circulating levels of MMP-2 (p < 0.05) in PF4-overexpressing transgenic mice, relative to controls. We also determined that PF4 induces the phosphorylation of NF-κB; notably, the suppression of NF-κB signaling by the inhibitor BAY 11-7082 abrogated PF4-induced MMP-2 upregulation. Moreover, the inhibition of surface glycosaminoglycans (GAGs) blocked both PF4 binding and NF-κB phosphorylation. Partial blockade of PF4 binding to the cells was achieved by treatment with either chondroitinase ABC or heparinase III, suggesting that both chondroitin sulfate and heparan sulfate mediate PF4 signaling. These results identify a novel pathway in which PF4 upregulates MMP-2 release from fibroblasts in an NF-κB- and GAG-dependent manner, and further our comprehension of the role of platelet signaling in periodontal tissue homeostasis.

Abstract
Glycosaminoglycans (GAGs) are consistently present in the human colon in free forms and as part of proteoglycans. Their utilization is critical for the colonization and proliferation of gut bacteria and also the health of hosts. Hence, it is essential to determine the GAG-degrading members of the gut bacteria and their enzymatic machinery for GAG depolymerization. In this review, we have summarized the reported GAG utilizers from Bacteroides and presented their polysaccharide utilization loci (PUL) and related enzymatic machineries for the degradation of chondroitin and heparin/heparan sulfate. Although similar comprehensive knowledge of GAG degradation is not available for other gut phyla, we have specified recently isolated GAG degraders from gut Firmicutes and Proteobacteria, and analyzed their genomes for the presence of putative GAG PULs. Deciphering the precise GAG utilization mechanism for various phyla will augment our understanding of their effects on human health.

Abstract
Enzymatic preparation of low-molecular-weight chondroitin sulfate (LMWCS) has received increasing attention. In this work, a chondroitin sulfate lyase ABC (Chon-ABC) was successfully cloned, expressed, and characterized. The Km and Vmax of the Chon-ABC were 0.54 mM and 541.3 U mg−1, respectively. The maximal activity was assayed as 500.4 U mg−1 at 37 °C in pH 8.0 phosphate buffer saline. The half-lives of the Chon-ABC were 133 d and 127 min at 4 °C and 37 °C, respectively. Enzymatic preparation of LMWCS was performed at room temperature for 30 min. The changes between the substrate and product were analyzed with mass spectrometry (MS), high-performance liquid chromatography (HPLC), gel permeation chromatography (GPC), and nuclear magnetic resonance (NMR). Overall, the Chon-ABC from Bacteroides thetaiotaomicron is competitive in large-scale enzymatic preparation of LMWCS for its high activity, stability, and substrate specificity.

Abstract
Glucuronan lyases (EC 4.2.2.14) catalyze depolymerization of linear β-(1,4)-polyglucuronic acid (glucuronan). Only a few glucuronan lyases have been characterized until now, most of them originating from bacteria. Here we report the discovery, recombinant production, and functional characterization of the full complement of six glucuronan specific polysaccharide lyases in the necrotic mycoparasite Trichoderma parareesei. The enzymes belong to four different polysaccharide lyase families and have different reaction optima and glucuronan degradation profiles. Four of them showed endo-lytic action and two, TpPL8A and TpPL38A, displayed exo-lytic action. Nuclear magnetic resonance revealed that the monomeric end product from TpPL8A and TpPL38A underwent spontaneous rearrangements to tautomeric forms. Proteomic analysis of the secretomes from T. parareesei growing on pure glucuronan and lyophilized A. bisporus fruiting bodies, respectively, showed secretion of five of the glucuronan lyases and high-performance anion-exchange chromatography with pulsed amperometric detection analysis confirmed the presence of glucuronic acid in the A. bisporus fruiting bodies. By systematic genome annotation of more than 100 fungal genomes and subsequent phylogenetic analysis of the putative glucuronan lyases, we show that glucuronan lyases occur in several ecological and taxonomic groups in the fungal kingdom. Our findings suggest that a diverse repertoire of glucuronan lyases is a common trait among Hypocreales species with mycoparasitic and entomopathogenic lifestyles. IMPORTANCE This paper reports the discovery of a set of six complementary glucuronan lyase enzymes in the mycoparasite Trichoderma parareseei. Apart from the novelty of the discovery of these enzymes in T. parareesei, the key importance of the study is the finding that the majority of these lyases are induced when T. parareesei is inoculated on Basidiomycete cell walls that contain glucuronan. The study also reveals putative glucuronan lyase encoding genes in a wealth of other fungi that furthermore points at fungal cell wall glucuronan being a target C-source for many types of fungi. In a technical context, the findings may lead to controlled production of glucuronan oligomers for advanced pharmaceutical applications and pave the way for development of new fungal biocontrol agents.

Abstract
Glycosaminoglycan lyase is an effective tool for the functional studies of glycosaminoglycans and for the preparation of oligosaccharides. In this study, a new glycosaminoglycan lyase HCLaseV with a molecular weight of 90 kDa was cloned, expressed, and characterized from Vibrio sp. H240. The lyase belonged to the polysaccharide lyase (PL)- 8 family. HCLaseV showed enzyme activities toward chondroitin sulfate A, chondroitin sulfate B, chondroitin sulfate C, and hyaluronic acid. HCLaseV exhibited the highest activity against HA at pH 7.0 and 40 °C. HCLaseV was an endo-type enzyme whose degradation end-product was unsaturated disaccharides. Ca2+ inhibited the activity of HCLaseV to a certain extent, which was different from most of the enzymes in the PL-8 family. Mutagenesis studies showed that the Ca2+ inhibition might be related to the Asn244 residue. The sequence homology was evaluated by mutagenesis studies, and the catalytic residues in HCLaseV were presumed to be His278, Trp485, and Tyr287. These characteristics are helpful for further basic research and application.

Abstract
Chondroitinases, catalyzing the degradation of chondroitin sulfate (CS) into oligosaccharides, not only play a crucial role in understanding the structure and function of CS, but also have been reported as a potential candidate drug for the treatment of high CS-related diseases. Here, a marine bacterium Vibrio hyugaensis LWW-1 was isolated, and its genome was sequenced and annotated. A chondroitinase, VhChlABC, was found to belong to the second subfamily of polysaccharide lyase (PL) family 8. VhChlABC was recombinant expressed and characterized. It could specifically degrade CS-A, CS-B, and CS-C, and reached the maximum activity at pH 7.0 and 40 °C in the presence of 0.25 M NaCl. VhChlABC showed high stability within 8 h under 37 °C and within 2 h under 40 °C. VhChlABC was stable in a wide range of pH (5.0~10.6) at 4 °C. Unlike most chondroitinases, VhChlABC showed high surfactant tolerance, which might provide a good tool for removing extracellular CS proteoglycans (CSPGs) of lung cancer under the stress of pulmonary surfactant. VhChlABC completely degraded CS to disaccharide by the exolytic mode. This research expanded the research and application system of chondroitinases.

Abstract
Hyaluronic acid (HA) is a negatively charged and linear polysaccharide existing in the tissues and body fluids of all vertebrates. Some pathogenic bacteria target hyaluronic acid for adhesion and/or infection to host cells. Vibrio alginolyticus is an opportunistic pathogen related to infections of humans and marine animals, and the hyaluronic acid-degrading potential of Vibrio spp. has been well-demonstrated. However, little is known about how Vibrio spp. utilize hyaluronic acid. In this study, a marine bacterium V. alginolyticus LWW-9 capable of degrading hyaluronic acid has been isolated. Genetic and bioinformatic analysis showed that V. alginolyticus LWW-9 harbors a gene cluster involved in the degradation, transport, and metabolism of hyaluronic acid. Two novel PL8 family hyaluronate lyases, VaHly8A and VaHly8B, are the key enzymes for the degradation of hyaluronic acid. VaHly8A and VaHly8B have distinct biochemical properties, reflecting the adaptation of the strain to the changing parameters of the aquatic habitats and hosts. Based on genomic and functional analysis, we propose a model for the complete degradation of hyaluronic acid by V. alginolyticus LWW-9. Overall, our study expands our knowledge of the HA utilization paradigm within the Proteobacteria, and the two novel hyaluronate lyases are excellent candidates for industrial applications.

Abstract
Chondroitin sulfate proteoglycans inhibit regeneration, neuroprotection, and plasticity following spinal cord injury. The development of a second-generation chondroitinase ABC enzyme, capable of being secreted from mammalian cells (mChABC), has facilitated the functional recovery of animals following severe spinal trauma. The genetically modified enzyme has been shown to efficiently break down the inhibitory extracellular matrix surrounding cells at the site of injury, while facilitating cellular integration and axonal growth. However, the activity profile of the enzyme in relation to the original bacterial chondroitinase (bChABC) has not been determined. Here, we characterize the activity profile of mChABC and compare it to bChABC, both enzymes having been maintained under physiologically relevant conditions for the duration of the experiment. We show that this genetically modified enzyme can be secreted reliably and robustly in high yields from a mammalian cell line. The modifications made to the cDNA of the enzyme have not altered the functional activity of mChABC compared to bChABC, ensuring that it has optimal activity on chondroitin sulfate-A, with an optimal pH at 8.0 and temperature at 37 °C. However, mChABC shows superior thermostability compared to bChABC, ensuring that the recombinant enzyme operates with enhanced activity over a variety of physiologically relevant substrates and temperatures compared to the widely used bacterial alternative without substantially altering its kinetic output. The determination that mChABC can function with greater robustness under physiological conditions than bChABC is an important step in the further development of this auspicious treatment strategy toward a clinical application.

[PMID: 33375969 DOI: 10.1016/j.enzmictec.2020.109701] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 10/16/2020] [Accepted: 11/03/2020] [Indexed: 11/29/2022]
Abstract
Chondroitinase ABC can be used to prepare chondroitin sulfate (CS) oligosaccharides efficiently and environmentally. It also promotes nerve recovery through enzymatic degradation of glycosaminoglycan chains in damaged nerve tissue. In this study, two new chondroitin sulfate ABC lyases were expressed and characterized from Edwardsiella tarda LMG2793, with molecular weight of 116.8 kDa and 115.9 kDa, respectively. Two lyases ChABC I and ChABC II belonged to the polysaccharide lyase (PL) family 8. ChABC I and ChABC II showed enzyme activity towards chondroitin sulfate A (CS-A), CS-B, CS-C and CS-D, but had no activity towards hyaluronan (HA). The optimal temperature for ChABC I to exhibit the highest activity against CS-A was 40 °C and the optimal pH was 7.0. ChABC II showed the highest activity to CS-A at optimal temperature of 40 °C and pH of 9.0. ChABC I and ChABC II were stable at 37 °C and remained about 90 % of activity after incubation at 37 °C for 3 h. Many metal ions had no effect on the activity of ChABC I and ChABC II. These properties were beneficial to their further basic research and application. ChABC I was an endo-type enzyme while ChABC II was an exo-type enzyme. A group of amino acids were selected for further study by evaluating the sequence homology with other CS degradation lyases. Mutagenesis studies speculated that the catalytic residues in ChABC I were His522, Tyr529 and Arg581. The catalytic residues of ChABC II were His498, Tyr505 and Arg558. This work will contribute to the structural and functional characterization of biomedically relevant CS and promote the application of CS lyase in further basic research and therapeutics.

Abstract
Chondroitin sulfate (CS)/dermatan sulfate (DS) lyases play important roles in structural and functional studies of CS/DS. In this study, a novel CS/DS lyase (enCSase) was identified from the genome of the marine bacterium Photobacterium sp. QA16. This enzyme is easily heterologously expressed and purified as highly active form against various CS, DS and hyaluronic acid (HA). Under the optimal conditions, the specific activities of this enzyme towards CSA, CSC, CSD, CSE, DS and HA were 373, 474, 171, 172, 141 and 97 U/mg of proteins, respectively. As an endolytic enzyme, enCSase degrades HA to unsaturated hexa- and tetrasaccharides but CS/DS to unsaturated tetra- and disaccharides as the final products. Sequencing analysis showed that the structures of tetrasaccharides in the final products of CS variants were not unique but were highly variable, indicating the randomness of substrate degradation by this enzyme. Further studies showed that the smallest substrate of enCSase was octasaccharide for HA but hexasaccharide for CS/DS, which could explain why this enzyme cannot degrade HA hexa- and tetrasaccharides and CS/DS tetrasaccharides further. It is believed that enCSase may be a very useful tool for structural and functional studies and related applications of CS/DS and HA.

Abstract
Chondroitinases degrade chondroitin sulfate (CS) into oligosaccharides, of which the biological activities have vital roles in various fields. Some chondroitinases in polysaccharide lyase family 8 (PL8) have been classified into four subfamilies (PL8_1, PL8_2, PL8_3, and PL8_4) based on their sequence similarity and substrate specificities. In this study, a gene, vpa_0049, was cloned from marine bacterium Vibrio sp. QY108. The encoded protein, Vpa_0049, did not belong to the four existing subfamilies in PL8 based on phylogenetic analysis. Vpa_0049 could degrade various glycosaminoglycans (CS-A, CS-B, CS-C, CS-D, and HA) into unsaturated disaccharides in an endolytic manner, which was different from PL8 lyases of four existing subfamilies. The maximum activity of Vpa_0049 on different glycosaminoglycan substrates appeared at 30-37 °C and pH 7.0-8.0 in the presence of NaCl. Vpa_0049 showed approximately 50% of maximum activity towards CS-B and HA at 0 °C. It was stable in alkaline conditions (pH 8.0-10.6) and 0-30 °C. Our study provides a new broad-substrate chondroitinase and presents an in-depth understanding of PL8.

Abstract
Glycosaminoglycan (GAG) lyase is an effective tool for the structural and functional studies of glycosaminoglycans and preparation of functional oligosaccharides. A new GAG lyase from Microbacterium sp. H14 was cloned, expressed, purified, and characterized, with a molecular weight of approximately 85.9 kDa. The deduced lyase HCLaseM belonged to the polysaccharide lyase (PL) family 8. Based on the phylogenetic tree, HCLaseM could not be classified into the existing three subfamilies of this family. HCLaseM showed almost the same enzyme activity towards hyaluronan (HA), chondroitin sulfate A (CS-A), CS-B, CS-C, and CS-D, which was different from reported GAG lyases. HCLaseM exhibited the highest activities to both HA and CS-A at its optimal temperature (35 °C) and pH (pH 7.0). HCLaseM was stable in the range of pH 5.0–8.0 and temperature below 30 °C. The enzyme activity was independent of divalent metal ions and was not obviously affected by most metal ions. HCLaseM is an endo-type enzyme yielding unsaturated disaccharides as the end products. The facilitated diffusion effect of HCLaseM is dose-dependent in animal experiments. These properties make it a candidate for further basic research and application.

Abstract
Chondroitinase (ChSase), a type of glycosaminoglycan (GAG) lyase, can degrade chondroitin sulfate (CS) to unsaturate oligosaccharides, with various functional activities. In this study, ChSase AC II from a newly isolated marine bacterium Arthrobacter sp. CS01 was cloned, expressed in Pichia pastoris X33, purified, and characterized. ChSase AC II, with a molecular weight of approximately 100 kDa and a specific activity of 18.7 U/mg, showed the highest activity at 37 °C and pH 6.5 and maintained stability at a broad range of pH (5–7.5) and temperature (below 35 °C). The enzyme activity was increased in the presence of Mn2+ and was strongly inhibited by Hg2+. Moreover, the kinetic parameters of ChSase AC II against CS-A, CS-C, and HA were determined. TLC and ESI-MS analysis of the degradation products indicated that ChSase AC II displayed an exolytic action mode and completely hydrolyzed three substrates into oligosaccharides with low degrees of polymerization (DPs). All these features make ChSase AC II a promising candidate for the full use of GAG to produce oligosaccharides.

Abstract
Glycosaminoglycans (GAGs) and GAG-degrading enzymes have wide-ranging applications in the medical and biotechnological industries. The former are also an important nutrient source for select species of the human gut microbiota (HGM), a key player in host-microbial interactions. How GAGs are metabolized by the HGM is therefore of interest and has been extensively investigated in the model human gut microbe Bacteroides thetaiotaomicron. The presence of as-yet uncharacterized GAG-inducible genes in its genome and of related species, however, is testament to our incomplete understanding of this process. Nevertheless, it presents a potential opportunity for the discovery of additional GAG-degrading enzymes. Here, we investigated a gene of unknown function (BT_3328) from the chondroitin sulfate (CS) utilization locus of B. thetaiotaomicron NMR and UV spectroscopic assays revealed that it encodes a novel polysaccharide lyase (PL), hereafter referred to as BtCDH, reflecting its source (B. thetaiotaomicron (Bt)) and its ability to degrade the GAGs CS, dermatan sulfate (DS), and hyaluronic acid (HA). When incubated with HA, BtCDH generated a series of unsaturated HA sugars, including Δ4,5UA-GlcNAc, Δ4,5UA-GlcNAc-GlcA-GlcNac, Δ4,5UA-[GlcNAc-GlcA]2-GlcNac, and Δ4,5UA-[GlcNAc-GlcA]3-GlcNac, as end products and hence was classed as endo-acting. A combination of genetic and biochemical assays revealed that BtCDH localizes to the cell surface of B. thetaiotaomicron where it enables extracellular GAG degradation. BtCDH homologs were also detected in several other HGM species, and we therefore propose that it represents the founding member of a new polysaccharide lyase family (PL29). The current discovery also contributes new insights into CS metabolism by the HGM.

Abstract
The pharmacokinetic profile of a new 800-mg tablet of nonanimal chondroitin sulfate (CS) (Mythocondro®, 800-mg tablets, Gnosis S.p.A., Italy) was investigated vs an animal CS in healthy volunteers for a total period of 48 hours. After a single 2400-mg dose of the test and the reference formulation, total CS, the compositional disaccharides (ΔDi6S, ΔDi4S and ΔDi0S), and the overall charge density were quantified in plasma. The safety and tolerability profile after a single dose of this new nonanimal CS tablets was excellent. After baseline-corrected concentrations, an overall greater plasma concentration was observed after 24 hours of ∼44% and after 48 hours of ∼45% from administration of nonanimal when compared to animal-derived CS. Moreover, nonanimal CS increases the specific sulfation in the 6-position of N-acetyl-galactosamine in human plasma CS and, as a consequence, the overall charge density, reaching double values (0.91), after 48 hours compared to bovine CS and to endogenous CS. In conclusion, nonanimal CS, possessing a lower molecular weight than an animal-derived sample, produces a greater CS concentration for a more prolonged period of time in plasma and an increase in charge density and specific 6-sulfation of endogenous plasma CS.

Glycoconj J 2016; 33:181-8.

Abstract
In this study, the content, structure and residual percentages of glycosaminoglycans (GAGs) in the feces of seven breastfed newborns after ingesting a known amount of milk were studied. A comparison was made with five newborns fed with formula milk. Characterization of GAGs from milk and feces samples was performed according to previous methodology. Compared to the ingested GAGs present in milk, residual feces GAGs of breastfed newborns were <0.4 %, contrary to formula milk fed children, where the residues were ~4 %. As a consequence, >99 % of human milk GAGs are utilized as opposed to ~96 % of formula milk. Hyaluronic acid utilization was found to be fairly similar contrary to chondroitin sulfate/dermatan sulfate and heparan sulfate, which were found to be ~10-18 times lower in formula milk fed children. Our new results further demonstrate that the elevated content of human milk GAGs passes undigested through the entire digestive system of newborns, possibly protecting the infant from infections. In the distal gastrointestinal tract, these complex macromolecules are catabolized by a cohort of bacterial enzymes and constituent monosaccharides/oligosaccharides utilized for further metabolic purposes potentially useful for bacteria metabolism or internalized by intestinal cells. Thanks to their elevated structural heterogeneity, milk GAGs are used differently depending on their distinct primary structure. Finally, a different utilization and availability was observed for human milk GAGs compared to formula milk due to their various composition and structural heterogeneity.

Abstract
Polysaccharide lyases (PLs) have been assigned to 21 families based on their sequences, with ~ 50 singletons awaiting further classification. For 19 of these families, the structure of at least one protein is known. In this review, we have analyzed the available structural information and show that presently known PL families belong to six general folds. Only two general catalytic mechanisms have been observed among these PLs: (1) metal-assisted neutralization of the acidic group of the sugar next to the cleaved bond, with, rather unusually, arginine or lysine playing the role of Brønsted base and (2) neutralization of the acidic group on the sugar by a close approach of an amino or acidic group forcing its protonation and Tyr or Tyr-His acting as the Brønsted base and acid.

Liquid chromatography-mass spectrometry to study chondroitin lyase action pattern. Anal Biochem 2008; 385:57-64.

Abstract
Liquid chromatography-mass spectrometry was applied to determine the action pattern of different chondroitin lyases. Two commercial enzymes, chondroitinase ABC (Proteus vulgaris) and chondroitinase ACII (Arthrobacter aurescens), having action patterns previously determined by viscosimetry and gel electrophoresis were first examined. Next, the action patterns of recombinant lyases, chondroitinase ABC from Bacteroides thetaiotaomicron (expressed in Escherichia coli) and chondroitinase AC from Flavobacterium heparinum (expressed in its original host), were examined. Chondroitin sulfate A (CS-A, also known as chondroitin-4-sulfate) was used as the substrate for these four lyases. Aliquots taken at various time points were analyzed. The products of chondroitinase ABC (P. vulgaris) and chondroitinase AC (F. heparinum) contained unsaturated oligosaccharides of sizes ranging from disaccharide to decasaccharide, demonstrating that both are endolytic enzymes. The products afforded by chondroitinase ABC (B. thetaiotaomicron) and chondroitinase ACII (A. aurescens) contained primarily unsaturated disaccharide. These two exolytic enzymes showed different minor products, suggesting some subtle specificity differences between the actions of these two exolytic lyases on chondroitin sulfate A.
