In vitro biochemical characterization and genotoxicity assessment of Sapindus saponaria seed extract. JOURNAL OF ETHNOPHARMACOLOGY 2021; 276:114170. [PMID: 33932515 DOI: 10.1016/j.jep.2021.114170] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 04/23/2021] [Accepted: 04/24/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sapindus saponaria, also popularly known as soapberry, has been used in folk medicinal values because of its therapeutic properties and several compounds in its composition, which represent a target in potential for drug discovery. However, few data about its potential toxicity has been reported. AIM OF THE STUDY Plant proteins can perform essential roles in survival, acting as defense mechanism, as well functioning as important molecular reserves for its natural metabolism. The aim of the current study was to investigate the in vitro toxicity profile of protein extract of S. saponaria and detect protein potentially involved in biological effects such as collagen hydrolysis and inhibition of viral proteases. MATERIALS AND METHODS Protein extract of soapberry seeds was investigated for its cytotoxic and genotoxic action using the Ames test. The protein extract was also subjected to a partial purification process of a protease and a protease inhibitor by gel chromatography filtration techniques and the partially isolated proteins were characterized biochemically. RESULTS Seed proteins extract of S. saponaria was evaluated until 100 μg/mL concentration, presenting cytotoxicity and mutagenicity in bacterial model mostly when exposed to exogenous metabolic system and causing cytotoxic and genotoxic effects in HepG2 cells. The purification and partial characterization of a serine protease (43 kDa) and a cysteine protease inhibitor (32.8 kDa) from protein extract of S. Saponaria, corroborate the idea of the biological use of the plant as an insecticide and larvicide. Although it shows cytotoxic, mutagenic and genotoxic effects. CONCLUSION The overall results of the present study provide supportive data on the potential use of proteins produced in S. saponaria seeds as pharmacological and biotechnological agents that can be further explored for the development of new drugs.

Abstract
Molecular farming increasingly uses the tobacco relative Nicotiana benthamiana for production of recombinant proteins through transient expression. Several proteins are produced efficiently with this expression platform, but yields for other proteins are often very low. These low yields are frequently due to endogenous proteases. The latest genome annotations indicate that N. benthamiana encodes for at least 1243 putative proteases that probably act redundantly and consecutively on substrates in different subcellular compartments. Here, we discuss the N. benthamiana protease repertoire that may affect recombinant protein production and recent advances in protease depletion strategies to increase recombinant protein production in N. benthamiana.

Abstract
Seed exudates are plant-derived natural bioactive compounds consisting of a complex mixture of organic and inorganic molecules. Plant seed exudates have been poorly studied against parasite nematodes. This study was undertaken to identify proteins in the Myracrodruon urundeuva seed exudates and to assess the anthelmintic activity against Haemonchus contortus, an important parasite of small ruminants. M. urundeuva seed exudates (SEX) was obtained after immersion of seeds in sodium acetate buffer. SEX was fractionated with ammonium sulfate at 0–90% concentration to generate the ressuspended pellet (SEXF1) and the supernatant (SEXF2). SEX, SEXF1, and SEXF2 were exhaustively dialyzed against distilled water (cut-off: 12 kDa) and the protein contents determined. Mass spectrometry analyses of SEX, SEXF1, and SEXF2 were done to identify proteins and secondary metabolites. The seed exudates contained protease, protease inhibitor, peptidase, chitinase, and lipases as well as the low molecular weight secondary compounds ellagic acid and quercetin rhamnoside. SEX inhibited H. contortus larval development (LDA) (IC50 = 0.29 mg mL-1), but did not affect larval exsheathment (LEIA). On the other hand, although SEXF1 and SEXF2 inhibited H. contortus LEIA (IC50 = 1.04 and 0.93 mg mL-1, respectively), they showed even greater inhibition efficiency of H. contortus larval development (IC50 = 0.29 and 0.42 mg mL-1, respectively). To the best of our knowledge, this study is the first to show the anthelmintic activity of plant exudates against a gastrointestinal nematode. Moreover, it suggests the potential of exuded proteins as candidates to negatively interfere with H. contortus life cycle.

JOURNAL OF PLANT PHYSIOLOGY 2017; 211:70-80.

Abstract
Subtilases are one of the largest groups of the serine protease family and are involved in many aspects of plant development including senescence. In wheat, previous reports demonstrate an active participation of two senescence-induced subtilases, denominated P1 and P2, in nitrogen remobilization during whole plant senescence. The aim of the present study was to examine the participation of subtilases in senescence-associated proteolysis of barley leaves while comparing different senescence types. With this purpose, subtilase enzymatic activity, immunodetection with a heterologous antiserum and gene expression of 11 subtilase sequences identified in barley databases by homology to P1 were analyzed in barley leaves undergoing dark-induced or natural senescence at the vegetative or reproductive growth phase. Results showed that subtilase specific activity as well as two inmunoreactive bands representing putative subtilases increased in barley leaves submitted to natural and dark-induced senescence. Gene expression analysis showed that two of the eleven subtilase genes analyzed, HvSBT3 and HvSBT6, were up-regulated in all the senescence conditions tested while HvSBT2 was expressed and up-regulated only during dark-induced senescence. On the other hand, HvSBT1, HvSBT4 and HvSBT7 were down-regulated during senescence and two other subtilase genes (HvSBT10 and HvSBT11) showed no significant changes. The remaining subtilase genes were not detected. Results demonstrate an active participation of subtilases in protein degradation during dark-induced and natural leaf senescence of barley plants both at the vegetative and reproductive stage, and, based on their expression profile, postulate HvSBT3 and HvSBT6 as key components of senescence-associated proteolysis.

PLANT MOLECULAR BIOLOGY 2016; 92:193-207.

Abstract
Phytocystatins are well-known inhibitors of C1A cysteine proteinases. However, previous research has revealed legumain (C13) protease inhibition via a carboxy-extended phytocystatin. Among the 12 phytocystatins genes in rice, OcXII is the only gene possessing this carboxy-terminal extension. The specific legumain inhibition activity was confirmed, in our work, using a recombinant OcXII harboring only the carboxy-terminal domain and this part did not exhibit any effect on papain-like activities. Meanwhile, rice plants silenced at the whole OcXII gene presented higher legumain and papain-like proteolytic activities, resulting in a faster initial seedling growth. However, when germinated under stressful alkaline conditions, OcXII-silenced plants exhibited impaired root formation and delayed shoot growth. Interestingly, the activity of OcXII promoter gene was detected in the rice seed scutellum region, and decreases with seedling growth. Seeds from these plants also exhibited slower growth at germination under ABA or alkaline conditions, while maintaining very high levels of OcXII transcriptional activation. This likely reinforces the proteolytic control necessary for seed germination and growth. In addition, increased legumain activity was detected in OcXII RNAi plants subjected to a fungal elicitor. Overall, the results of this study highlight the association of OcXII with not only plant development processes, but also with stress response pathways. The results of this study reinforce the bifunctional ability of carboxy-extended phytocystatins in regulating legumain proteases via its carboxy-extended domain and papain-like proteases by its amino-terminal domain.

Abstract
Plants, as stationary organisms, have developed mechanisms allowing them efficient resource reallocation and a response to changing environmental conditions. One of these mechanisms is proteome remodeling via a broad peptidase network present in various cellular compartments including mitochondria and chloroplasts. The genome of the model plant Arabidopsis thaliana encodes as many as 616 putative peptidase-coding genes organized in 55 peptidase families. In this study, we describe the M3A family of peptidases, which comprises four members: mitochondrial and chloroplastic oligopeptidase (OOP), cytosolic oligopeptidase (CyOP), mitochondrial octapeptidyl aminopeptidase 1 (Oct1) and plant-specific protein of M3 family (PSPM3) of unknown function. We have analyzed the evolutionary conservation of M3A peptidases across plant species and the functional specialization of the three distinct subfamilies. We found that the subfamily-containing OOP and CyOP-like peptidases, responsible for oligopeptide degradation in the endosymbiotic organelles (OOP) or in the cytosol (CyOP), are highly conserved in all kingdoms of life. The Oct1-like peptidase subfamily involved in pre-protein maturation in mitochondria is conserved in all eukaryotes, whereas the PSPM3-like protein subfamily is strictly conserved in higher plants only and is of unknown function. Specific characteristics within PSPM3 sequences, i.e. occurrence of a N-terminal transmembrane domain and amino acid changes in distal substrate-binding motif, distinguish PSPM3 proteins from other members of M3A family. We performed peptidase activity measurements to analyze the role of substrate-binding residues in the different Arabidopsis M3A paralogs.

Abstract
Insufficient and/or improper protein degradation is associated with the development of various human pathologies. Enzymatic therapy with proteolytic enzymes aimed to improve insufficient proteolytic activity was suggested as a treatment of protease deficiency-induced disorders. Since in many cases human degradome is incapable of degrading the entire target protein(s), other organisms can be used as a source of proteases exhibiting activities distinct from human enzymes, and plants are perspective candidates for this source. In this study recombinant wheat cysteine protease Triticain-α was shown to refold in vitro into an autocatalytically activated proteolytic enzyme possessing glutenase and collagenase activities at acidic (or close to neutral) pH levels at the temperature of human body. Mass-spectrometry analysis of the products of Triticain-α-catalyzed gluten hydrolysis revealed multiple cleavage sites within the sequences of gliadin toxic peptides, in particular, in the major toxic 33-mer α-gliadin-derived peptide initiating inflammatory responses to gluten in celiac disease (CD) patients. Triticain-α was found to be relatively stable in the conditions simulating stomach environment. We conclude that Triticain-α can be exploited as a basic compound for development of (i) pharmaceuticals for oral administration aimed at release of the active enzyme into the gastric lumen for CD treatment, and (ii) topically active pharmaceuticals for wound debridement applications.

Abstract
Plants are promising hosts for the production of monoclonal antibodies (mAbs). However, proteolytic degradation of antibodies produced both in stable transgenic plants and using transient expression systems is still a major issue for efficient high-yield recombinant protein accumulation. In this work, we have performed a detailed study of the degradation profiles of two human IgG1 mAbs produced in plants: an anti-HIV mAb 2G12 and a tumour-targeting mAb H10. Even though they use different light chains (κ and λ, respectively), the fragmentation pattern of both antibodies was similar. The majority of Ig fragments result from proteolytic degradation, but there are only a limited number of plant proteolytic cleavage events in the immunoglobulin light and heavy chains. All of the cleavage sites identified were in the proximity of interdomain regions and occurred at each interdomain site, with the exception of the VL /CL interface in mAb H10 λ light chain. Cleavage site sequences were analysed, and residue patterns characteristic of proteolytic enzymes substrates were identified. The results of this work help to define common degradation events in plant-produced mAbs and raise the possibility of predicting antibody degradation patterns 'a priori' and designing novel stabilization strategies by site-specific mutagenesis.

Abstract
Background Peptidases are key proteins involved in essential plant physiological processes. Although protein peptidase inhibitors are essential molecules that modulate peptidase activity, their global presence in different plant species remains still unknown. Comparative genomic analyses are powerful tools to get advanced knowledge into the presence and evolution of both, peptidases and their inhibitors across the Viridiplantae kingdom. Results A genomic comparative analysis of peptidase inhibitors and several groups of peptidases in representative species of different plant taxonomic groups has been performed. The results point out: i) clade-specific presence is common to many families of peptidase inhibitors, being some families present in most land plants; ii) variability is a widespread feature for peptidase inhibitory families, with abundant species-specific (or clade-specific) gene family proliferations; iii) peptidases are more conserved in different plant clades, being C1A papain and S8 subtilisin families present in all species analyzed; and iv) a moderate correlation among peptidases and their inhibitors suggests that inhibitors proliferated to control both endogenous and exogenous peptidases. Conclusions Comparative genomics has provided valuable insights on plant peptidase inhibitor families and could explain the evolutionary reasons that lead to the current variable repertoire of peptidase inhibitors in specific plant clades.

Abstract
A full-length cDNA encoding a putative aspartic acid protease (AcAP1) was isolated for the first time from the flesh of pineapple (Ananas comosus) fruit. The deduced sequence of AcAP1 showed all the common features of a typical plant aspartic protease phytepsin precursor. Analysis of AcAP1 gene expression under postharvest chilling treatment in two pineapple varieties differing in their resistance to blackheart development revealed opposite trends. The resistant variety showed an up-regulation of AcAP1 precursor gene expression whereas the susceptible showed a down-regulation in response to postharvest chilling treatment. The same trend was observed regarding specific AP enzyme activity in both varieties. Taken together our results support the involvement of AcAP1 in postharvest chilling stress resistance in pineapple fruits.

Abstract
Aqueous extracts of thistle flowers from the genus Cynara-Cardueae tribe Cass. (Cynareae Less.), Asteraceae Dumortier-are traditionally used in the Mediterranean region for production of artisanal cheeses. This is because of the presence of aspartic proteases (APs) with the ability to coagulate milk. Plant APs, collectively known as phytepsins (EC 3.4.23.40), are bilobed endopeptidases present in an ample variety of plant species with activity mainly at acidic pHs, and have two aspartic residues located on each side of a catalytic cleft that are responsible for catalysis. The cleavage of the scissile peptide-bond occurs primarily between residues with large hydrophobic side-chains. Even when aspartylendopeptidase activity in plants is normally present at relatively low levels overall, the flowers of several species of the Cardueae tribe possess APs with extremely high specific activities in certain tissues. For this reason, in the last two decades, APs present in thistle flowers have been the subject of intensive study. Present here is a compilation of work that summarizes the known chemical and biological properties of these proteases, as well as their biomedical and biotechnological applications.

Abstract
Metacaspases are distant relatives of the metazoan caspases, found in plants, fungi, and protists. However, in contrast with caspases, information about the physiological substrates of metacaspases is still scarce. By means of N-terminal combined fractional diagonal chromatography, the physiological substrates of metacaspase9 (MC9; AT5G04200) were identified in young seedlings of Arabidopsis thaliana on the proteome-wide level, providing additional insight into MC9 cleavage specificity and revealing a previously unknown preference for acidic residues at the substrate prime site position P1'. The functionalities of the identified MC9 substrates hinted at metacaspase functions other than those related to cell death. These results allowed us to resolve the substrate specificity of MC9 in more detail and indicated that the activity of phosphoenolpyruvate carboxykinase 1 (AT4G37870), a key enzyme in gluconeogenesis, is enhanced upon MC9-dependent proteolysis.
