Population-specific responses to pollution exposure suggest local adaptation of invasive red swamp crayfish Procambarus clarkii along the Mediterranean French coastline.

Abstract
Anthropogenic stressors can have an impact in a broad range of physiological processes and can be a major selective force leading to rapid evolution and local population adaptation. In this study, three populations of the invasive crayfish Procambarus clarkii were investigated. They are geographically separated for at least 20 years, and live in different abiotic environments: a freshwater inland lake (Salagou lake) with no major anthropogenic influence and two other coastal wetlands regularly polluted by pesticides along the Mediterranean coast (Camargue region and Bages-Sigean lagoon). Collected adults were genetically characterized using the mitochondrial COI gene and haplotype frequencies were analyzed for genetic variability within and between populations. Results revealed a higher genetic diversity for these invasive populations than any previous report in France, with more than seven different haplotypes in a single population. The contrasting genetic diversity between the Camargue and the other two populations suggest different times and sources of introduction. To identify differences in key physiological responses between these populations, individuals from each population were maintained in controlled conditions. Data on oxygen consumption rates indicate that the Salagou and Bages-Sigean populations possess a high inter-individual variability compared to the Camargue population. The low individual variability of oxygen consumption and low genetic diversity suggest a specific local adaptation for the Camargue population. Population-specific responses were identified when individuals were exposed to a pesticide cocktail containing azoxystrobin and oxadiazon at sublethal concentrations. The Salagou population was the only one with altered hydro-osmotic balance due to pollutant exposure and a change in protease activity in the hepatopancreas. These results revealed different phenotypic responses suggesting local adaptations at the population level.

Vogt G. Synthesis of digestive enzymes, food processing, and nutrient absorption in decapod crustaceans: a comparison to the mammalian model of digestion. ZOOLOGY 2021; 147:125945. [PMID: 34217027 DOI: 10.1016/j.zool.2021.125945] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Revised: 06/07/2021] [Accepted: 06/08/2021] [Indexed: 02/09/2023]
Abstract
The ∼15.000 decapod crustaceans that are mostly omnivorous have evolved a structurally and functionally complex digestive system. They have highly effective cuticular chewing and filtering structures in the stomach, which are regularly renewed by moulting. Decapods produce a broad range of digestive enzymes including chitinases, cellulases, and collagenases with unique properties. These enzymes are synthesized in the F-cells of the hepatopancreas and are encoded in the genome as pre-pro-proteins. In contrast to mammals, they are stored in a mature form in the lumen of the stomach to await the next meal, and therefore, the enzymes are particularly stable. The fat emulsifiers are fatty acyl-dipeptides rather than bile salts. After mechanical and chemical processing of the food in the cardiac stomach, the chyme is filtered by two unique filter systems of different mesh-size. The filtrate is then transferred to the hepatopancreas where the nutrients are absorbed by the R-cells, mostly via carriers, resembling nutrient absorption in the small intestine of mammals. The absorbed nutrients are used to fuel the metabolism of the hepatopancreas, are supplied to other organs, and are stored in the R-cells as glycogen and lipid reserves. Export lipids are secreted from the R-cells into the haemolymph as high density lipoproteins that mainly consist of phospholipids. In contrast to mammals, the midgut tube and hindgut contribute only little to food processing and nutrient absorption. The oesophagus, stomach and hindgut are well innervated but the hepatopancreas lacks nerves. Hormone cells are abundant in the midgut and hepatopancreas epithelia. Microorganisms are often present in the intestine of decapods, but they are apparently not essential for digestion and nutrition.

Abstract
Nowadays, enzymatic therapy is a very promising line of treatment for many different diseases. There is a group of disorders and conditions, caused by fibrotic and scar processes and associated with the excessive accumulation of collagen that needs to be catabolized to normalize the connective tissue content. The human body normally synthesizes special extracellular enzymes, matrix metalloproteases (MMPs) by itself. These enzymes can cleave components of extracellular matrix (ECM) and different types of collagen and thus maintain the balance of the connective tissue components. MMPs are multifunctional enzymes and are involved in a variety of organism processes. However, under pathological conditions, the function of MMPs is not sufficient, and these enzymes fail to deal with disease. Thus, medical intervention is required. Enzymatic therapy is a very effective way of treating such collagen-associated conditions. It involves the application of exogenous collagenolytic enzymes that catabolize excessive collagen at the affected site and lead to the successful elimination of disease. Such collagenolytic enzymes are synthesized by many organisms: bacteria, animals (especially marine organisms), plants and fungi. The most studied and commercially available are collagenases from Clostridium histolyticum and from the pancreas of the crab Paralithodes camtschatica, due to their ability to effectively hydrolyse human collagen without affecting other tissues, and their wide pH ranges of collagenolytic activity. In the present review, we summarize not only the data concerning existing collagenase-based medications and their applications in different collagen-related diseases and conditions, but we also propose collagenases from different sources for their potential application in enzymatic therapy.

Abstract
The autolysis of pretreated bovine skin (PBS) (treated with 0.1 M NaOH and 1% HCl), its endogenous proteases, inhibitors and their effects on quality attributes of gelatin were examined. PBS was subjected to different temperatures (20-90 °C) and pH (2-9) and treated with different protease inhibitors. Maximum autolytic activity of PBS was observed at 40 °C and pH 5. Ethylene-bis (oxyethylenenitrilo) tetraacetic acid (EGTA) was the most effective in impeding the degradation of γ-, β- and α- chains of PBS protein indicating that metallocollagenases were the predominant endogenous proteases in bovine skin. Gelatin was extracted in the absence (GAE) and presence (GPE) of EGTA, and EGTA with papain enzyme (GPEP). GPEP had a higher yield and lower gel strength than GEA and GPE. Metallocollagenases partook in the degradation of gelatin thereby affecting its functional properties. Pretreating PBS with or without EGTA, and papain influenced the quality attributes of gelatin.

Abstract
A chymotrypsin was purified from the gastric juice of California spiny lobster (Panulirus interrutpus), using preparative electrophoresis and affinity chromatography on agarose-p-aminobenzamidine. The molecular mass was estimated by polyacrylamide gel electrophoresis (SDS-PAGE) under denaturing conditions to be 28 kDa. Chymotrypsin activity was totally inhibited by phenylmethylsulfonyl fluoride (PMSF) and chymostatin. Lobster chymotrypsin had optimal pH 7.0-8.0 and temperature of 55 °C. The enzyme is highly stable under a wide range of pH (retaining up to 80 % of activity after 1 h of incubation at pH 3.0, 5.0, and 12.0), showing higher stability at pH 8.0, and was inactivated after 20 min at 55 °C. Lobster chymotrypsin was able to hydrolyze protein substrates at as low as pH 3.0. These results are consistent with the findings of enzyme stability. Activity was assessed after incubation of enzyme with different organic solvents (in the range of 10-50 %); when tested in the presence of acetone, ethanol, propanol, and butanol, lobster chymotrypsin residual activity was >80 %; whereas in the presence of dimethyl sulfoxide (DMSO) and toluene, lobster chymotrypsin residual activity was <80 %. Deduced amino acid sequence, corroborated by mass spectrometry, was determined.

Abstract
Chymotrypsin from shrimp, Penaeus californiensis, was compared to Bos taurus chymotrypsin, and its structure-function relationship was studied. Catalytic efficiency toward synthetic substrate is lower, but it has a broad specificity and higher activity toward protein substrates, including collagen. It is active at pH 4-10 and fully active up to 50 °C for 2 h and at least nine days at room temperature. The activation peptide is twice as long as bovine chymotrypsinogen, has less disulfide bridges, and is a single polypeptide. Only one activation step is necessary from chymotrypsinogen to the mature enzyme. Postmortem implications in muscle softening and melanisation, resistance to temperature and pH and efficiency with proteinaceous substrates make chymotrypsin useful as a biotechnological tool in food processing. This makes shrimp processing wastes useful as a material for production of fine reagents.

Abstract
We characterized major digestive enzymes in Panulirus argus using a combination of biochemical assays and substrate-(SDS or native)-PAGE. Protease and amylase activities were found in the gastric juice while esterase and lipase activities were higher in the digestive gland. Trypsin-like activity was higher than chymotrypsin-like activity in the gastric juice and digestive gland. Stability and optimal conditions for digestive enzyme activities were examined under different pHs, temperature and ionic strength. The use of protease inhibitors showed the prevalence of serine proteases and metalloproteases. Results for serine proteases were corroborated by zymograms where several isotrypsins-like (17-21 kDa) and isochymotrypsin-like enzymes (23-38 kDa) were identified. Amylases (38-47 kDa) were detected in zymograms and a complex array of non-specific esterases isoenzymes was found in the digestive gland. Isoenzyme polymorphism was found for trypsin, amylase, and esterase. This study is the first to evidence the biochemical bases of the plasticity in feeding habits of P. argus. Distribution and properties of enzymes provided some indication on how the digestion takes place and constitute baseline data for further studies on the digestion physiology of spiny lobsters.

Abstract
Many cyanobacteria produce peptides that inhibit mammalian proteases. The hypothesis that inhibitors of mammalian proteases produced by cyanobacteria also interfere with digestive proteases of natural cladoceran grazers was tested by comparing the effects of cyanobacterial protease inhibitors on digestive proteases from Daphnia magna and on commercially available bovine proteases. The major digestive proteases of D. magna are trypsins and chymotrypsins, which differ from those of bovine origin in substrate specificity and susceptibility to synthetic inhibitors. An extract from Microcystis aeruginosa strain PCC 7806 inhibited both types of D. magna proteases. Subsequent fractionation of the extract by high-performance liquid chromatography indicated that several inhibitors are produced by M. aeruginosa that differ in their specificity for the trypsins and chymotrypsins of D. magna. Two fractions differed in their inhibitory effect on proteases of D. magna and bovine origin; therefore, assessment of the impact of cyanobacterial protease inhibitors on natural communities requires the use of digestive proteases from ecologically relevant grazers.

Abstract
The paper describes the characterization of proteases in the whole body homogenate of Moina macrocopa, which can possibly be inhibited by the extracts of Microcystis aeruginosa PCC7806. With the use of oligopeptide substrates and specific inhibitors, we detected the activities of trypsin, chymotrypsin, elastase and cysteine protease. Cysteine protease, the predominant enzyme behind proteolysis of a natural substrate, casein, was partially purified by gel filtration. The substrate SDS-polyacrylamide gel electrophoresis of body homogenate revealed the presence of nine bands of proteases (17-72 kDa). The apparent molecular mass of an exclusive cysteine protease was 60 kDa, whereas of trypsin, it was 17-24 kDa. An extract of M. aeruginosa PCC7806 significantly inhibited the activities of trypsin, chymotrypsin and cysteine protease in M. macrocopa body homogenate at estimated IC(50) of 6- to 79-microg dry mass mL(-1). Upon fractionation by C-18 solid-phase extraction, 60% methanolic elute contained all the protease inhibitors, and these metabolites could be further separated by reverse-phase liquid chromatography. The metabolites inhibitory to M. macrocopa proteases also inhibited the corresponding class of proteases of mammalian/plant origin. The study suggests that protease inhibition may contribute to chemical interaction of cyanobacteria and crustacean zooplankton.

Abstract
Two major protease activities were present in gut homogenates of the cladoceran crustacean Daphnia magna: (i) a trypsin activity that hydrolysed the synthetic substrate N-benzoyl-dl-arginine p-nitroanilide and was strongly inhibited by N-p-tosyl-lysine chloroketone (TLCK) and 4-(amidinophenyl)methanesulfonyl fluoride (APMSF) and not inhibited by chymostatin; and (ii) a chymotrypsin activity that hydrolysed synthetic chymotrypsin substrates containing more than one amino acid, did not hydrolyse N-benzoyl-l-tyrosine p-nitroanilide, and was strongly inhibited by chymostatin and not by TLCK and APMSF. Both activities had alkaline pH optima (pH 7-10), but were shown to be due to distinct types of proteases. These two enzyme activities accounted for 75-83% of the proteolytic activity of gut contents. Substrate SDS-polyacrylamide gel electrophoresis revealed nine different proteases ranging from 15 to 73 kDa.

Abstract
BACKGROUND In this paper, we describe cDNA cloning of a new anionic trypsin and a collagenolytic serine protease from king crab Paralithodes camtschaticus and the elucidation of their primary structures. Constructing the phylogenetic tree of these enzymes was undertaken in order to prove the evolutionary relationship between them. RESULTS The mature trypsin PC and collagenolytic protease PC contain 237 (Mcalc 24.8 kDa) and 226 amino acid residues (Mcalc 23.5 kDa), respectively. Alignments of their amino acid sequences revealed a high degree of the trypsin PC identity to the trypsin from Penaeus vannamei (approximately 70%) and of the collagenolytic protease PC identity to the collagenase from fiddler crab Uca pugilator (76%). The phylogenetic tree of these enzymes was constructed. CONCLUSIONS Primary structures of the two mature enzymes from P. camtschaticus were obtained and compared with those of other proteolytic proteins, including some enzymes from brachyurans. A phylogenetic analysis was also carried out. These comparisons revealed that brachyurins are closely related to their vertebrate and bacterial congeners, occupy an intermediate position between them, and their study significantly contributes to the understanding of the evolution and function of serine proteases.

Abstract
Two different types of brachyurins, termed I and II, have been described in the literature. Within type I there are two subtypes, Ia and Ib. The prototype for the type I brachyurins is Fiddler crab collagenase I. Its cold-adapted analogue from Antarctic krill, termed euphaulysin, shares many of its characteristics. Both enzymes are distinguished by their broad substrate specificity as well as the ability to cleave collagen. The precursor form of euphaulysin has been expressed in Pichia pastoris and processed to its fully active form using cod trypsin. A molecular model of euphaulysin, based on the known crystal structure of crab collagenase I, indicates that the core structure of these enzymes is almost identical. As a cold-adapted enzyme, euphaulysin has a higher catalytic efficiency than crab collagenase I. It is also more sensitive to thermal inactivation and autolysis. Furthermore, euphaulysin has an increased length of several surface loops compared to crab collagenase I. Extended surface loops have been suggested to play a role in the cold activity of some bacterial enzymes. Sensitivity to autolysis is an important factor which contributes to the thermal instability of euphaulysin. Substitution of a highly exposed residue in the 'autolysis loop' of euphaulysin resulted in an increased stability of the enzyme towards thermal inactivation without altering its catalytic efficiency.

Abstract
The present study describes the activity and some characteristics of proteinases in the hepatopancreas of red shrimp Pleoticus muelleri during the different stages of the molting cycle. Proteolytic activity was highest between pH 7.5 and 8. The hepatopancreatic protein content in the premolt stage was higher than in the other stages of the molting cycle (P<0.05). No significant differences were found in total proteolytic activity in the hepatopancreas when comparing molting stages. The proteolytic activity of the P. muelleri hepatopancreas enzyme preparations is the main responsibility of serine proteinases. TLCK, a trypsin inhibitor, reduced azocasein hydrolysis between 26% (intermolt) and 37% (premolt). TPCK, a chymotrypsin inhibitor, did not decrease hydrolytic activity, except for in postmolt. Low trypsin and chymotrypsin activities were found during intermolt, and increased in postmolt. The electrophoretogram of the enzyme extracts shows 12 bands of activity during intermolt (from 16.6 to 53.1 kDa). Some fractions were not detected in the postmolt and premolt stages. Three low molecular weight trypsin forms (17.4, 19.1 and 20 kDa) were found in all molting stages. One band of chymotrypsin (21.9 kDa) was observed in all molting stages. High molecular mass active bands (66-205 kDa) could not be characterized with inhibitors. Comparison of the protease-specific activity of the hepatopancreas of some species indicated a relationship between digestive enzyme activity and feeding habits of the shrimp. Omnivorous shrimp, such as Penaeus vannamei (syn: Litopenaeus vannamei) and Penaeus monodon, showed higher protease activity than the carnivorous shrimp, Penaeus californiensis (syn: Farfantepenaeus californiensis) and P. muelleri. In fact, the enzymatic activity in the hepatopancreas of P. muelleri showed variations in relation to feeding habit and molting cycle.

Abstract
Euphauserase is a brachyurin type digestive enzyme isolated from Antarctic krill. The brachyurins belong to clan SA of the S1 family of serine endopeptidases. In this study, we demonstrate that the precursor form of recombinant euphauserase, termed pro-r-euphauserase, can be successfully expressed in Pichia pastoris. The presence of most of the 51-residue euphauserase propeptide is essential during expression, under the growth conditions of Pichia. The propeptide may be required either for correct folding or processing of the enzyme. Cod trypsin generates a fully active r-euphauserase from its precursor, which appears to be identical to the native enzyme. The mature r-euphauserase sequence contains 250 amino-acid residues including a 13-residue activation peptide, which seems to be attached to the molecule by a disulfide bond. Euphauserase shares an average sequence identity of 62% with its type I brachyurin analogue, crab collagenase I. However, the identity between these two sequences is much higher in the regions shown to be important for the broad substrate specificity and collagen binding of crab collagenase I. The type I brachyurins share only 30-40% identities with the type II brachyurins and trypsins. The low isoelectric point of euphauserase, with a calculated pI value of 3.9, is typical for the type I brachyurins.

Abstract
Two genomic DNA fragments encoding crustacean collagenolytic serine protease genes show coding fragments that span 1522-1526 base pairs and contain seven exons encoding the complete amino acid sequence of two enzymes, CHYA and CHYB. As in serine protease genes from other organisms, the region coding for the residues around the active site is split by two introns. Although the introns differ from those of other organisms in size and nucleotide sequence, their number and location are more or less the same as found in mammalian chymotrypsin or elastase genes that evolved lately, but different for trypsin genes. Meanwhile, the junction that occurs between the propeptide and the maturation site is only found in the shrimp genes. This is also the case for the junction located 13 amino acids after the active site aspartic acid in these genes. Between 40 and 50 copies of the genes are reported by Southern analysis. Seven different genes within ChyA Pv family present 0-6% base changes, whereas five different genes belonging to ChyB Pv family show changes of up to 27% in the short studied portion of exon 4. This last family presents a mosaic organization of the coding parts, which are also expressed in the hepatopancreas of the shrimp as the variant PVC5 cDNA.

Abstract
A serine collagenolytic protease was purified from a water soluble fraction of greenshore crab digestive gland by acidic precipitation, gel filtration on a Sephadex G-50 column, ion-exchange chromatography on a Fractogel TSK DEAE column, immobilized metal ion affinity chromatography (IMAC) on IDA (Cu2+) Sepharose 6B and ion-exchange chromatography on Hyper D column. The molecular mass of the monomeric Carcinus serine collagenase (CSC) was estimated to be 23,000 by SDS PAGE and its isoelectric point was found to be 4.0. The CSC is optimally active at pH 7 and 30 degrees C and is stable over a month at room temperature. The CSC activity is strongly inhibited by PMSF, 3,4-DCI, soybean trypsin inhibitor, alpha 1 proteinase inhibitor and elastatinal. The CSC hydrolyzes native collagen (Type I and III). CSC N-terminal sequence is similar to shrimp chymotrypsin-like protease and crab collagenolytic protease sequences. Kinetic parameters of the CSC were determined using some peptidyl-p-nitroanilides. The catalytic efficiency (kcat/Km) is Leu > Phe > Ala.

Abstract
Two chymotrypsin isoenzymes, ChT1 and ChT2 from cod pyloric caeca showed different kinetics against both chromogenic peptide and proteinaceous substrates. The enzymes have similar kcat values but ChT1 had substantially lower values for KM compared to ChT2. The enzymes also differed in cleaving site specificity with the oxidised B-chain of bovine insulin as substrate. ChT1 exhibited broader cleavage specificity compared to ChT2. This difference is parallel to the difference between chymotrypsin C and the A and B isotypes in higher animals. Direct N-terminal amino acid sequence analysis of the isoenzymes revealed that the active forms consisted of two polypeptide chains. The A chains were 13 residues long and ChT1 and ChT2 differed in three positions. The Cod enzyme A-chains differed from the A-chains of bovine chymotrypsin in four and five positions, respectively. The N-terminal part of the B-chains of the cod enzymes were nearly identical to that of the bovine A and B isoenzymes.

Abstract
A collagenolytic proteinase was purified from the intestines of Atlantic cod by (NH4)2SO4 fractionation, hydrophobic interaction chromatography (phenyl-Sepharose) and ion-exchange chromatography (DEAE-Sepharose). The proteinase has an estimated molecular weight of 24.1 (+/- 0.5) kDa as determined by SDS-PAGE and belongs to the chymotrypsin family of serine proteinases. The enzyme cleaves native collagen types I, III, IV and V, and also readily hydrolyzes succinyl-L-Ala-L-Ala-L-Pro-L-Phe-p-nitroanilide (sAAPFpna), an amide substrate of chymotrypsin, as well as succinyl-L-Ala-L-Ala-L-Pro-L-Leu-p-nitroanilide, a reported elastase substrate, but had no detectable activity towards several other substrates of these proteinases or of trypsin. The pH optimum of the enzyme was between pH 8.0 and 9.5 and it was unstable at pH values below 7. Maximal activity of the enzyme when assayed against sAAPFpna was centered between 45 and 50 degrees C. Calcium binding stabilized the cod collagenase against thermal inactivation, but even in the presence of calcium, the enzyme was unstable at temperatures above 30 degrees C.

Abstract
1. Two chymotrypsin variants, with collagenolytic activities, were purified from the hepatopancreas of Penaeus vannamei using radioactive protein as the substrate. 2. These proteases are very close as far as amino acid composition, molecular weight, inhibitors studies and specificity against small synthetic substrates are concerned. 3. N-terminal amino acid sequences of both variants are identical and are very close to other known crustacean serine proteases.

Abstract
1. We have investigated the collagenolytic activity of the following serine proteases: proteinase K, subtilisin Novo, Staphylococcal endoproteinase Glu-C, Streptomyces pronases, the trypsins and chymotrypsins from shrimp midgut and bovine pancreas. 2. By assays on both the insoluble 3H-collagen fibrils and the soluble type I collagen, it was demonstrated that the shrimp midgut serine proteases, and less efficiently, the pronases from Streptomyces griseus, could hydrolyze collagen while the other serine proteases tested could not. 3. Our data indicate that the trypsins and chymotrypsins of shrimp (Penaeus monodon) directly and indirectly digest native collagen, and that the indirect pathway probably involves activation of procollagenase in the native collagen by these serine proteases.
