Effects of Glycosylation on the Enzymatic Activity and Mechanisms of Proteases
International Journal of Molecular Sciences Review Effects of Glycosylation on the Enzymatic Activity and Mechanisms of Proteases Peter Goettig Structural Biology Group, Faculty of Molecular Biology, University of Salzburg, Billrothstrasse 11, 5020 Salzburg, Austria; [email protected]; Tel.: +43-662-8044-7283; Fax: +43-662-8044-7209 Academic Editor: Cheorl-Ho Kim Received: 30 July 2016; Accepted: 10 November 2016; Published: 25 November 2016 Abstract: Posttranslational modifications are an important feature of most proteases in higher organisms, such as the conversion of inactive zymogens into active proteases. To date, little information is available on the role of glycosylation and functional implications for secreted proteases. Besides a stabilizing effect and protection against proteolysis, several proteases show a significant influence of glycosylation on the catalytic activity. Glycans can alter the substrate recognition, the specificity and binding affinity, as well as the turnover rates. However, there is currently no known general pattern, since glycosylation can have both stimulating and inhibiting effects on activity. Thus, a comparative analysis of individual cases with sufficient enzyme kinetic and structural data is a first approach to describe mechanistic principles that govern the effects of glycosylation on the function of proteases. The understanding of glycan functions becomes highly significant in proteomic and glycomic studies, which demonstrated that cancer-associated proteases, such as kallikrein-related peptidase 3, exhibit strongly altered glycosylation patterns in pathological cases. Such findings can contribute to a variety of future biomedical applications.

JASON MARC GOLDSTEIN the Isolation, Characterization
JASON MARC GOLDSTEIN The Isolation, Characterization and Cloning of Three Novel Peptidases From Streptoccocus gordonii: Their Potential Roles in Subacute Bacterial Endocarditis (Under the Direction of JAMES TRAVIS) Streptococcus gordonii is generally considered a benign inhabitant of the oral microflora yet is a primary etiological agent in the development of subacute bacterial endocarditis (SBE), an inflammatory state that propagates thrombus formation and tissue damage on the surface of heart valves. Colonization and adherence mechanisms have been identified, yet factors necessary to sustain growth remain unidentified. Strain FSS2 produced three extracellular aminopeptidase activities during growth in neutral pH- controlled batch cultures. The first included a serine-class dipeptidyl-aminopeptidase, an x-Pro DPP (Sg-xPDPP) found as an 85 kDa monomer by SDS-PAGE while appearing as a homodimer under native conditions. Kinetic studies indicated a unique and stringent x- Pro specificity comparable to the DPPIV/CD26 and lactococcal x-Pro DPP families. Isolation of the full-length gene uncovered a 759-amino acid polypeptide with a mass of 87,115 Da and theoretical pI of 5.6. Significant homology was found with PepX gene family members from Lactobacillus ssp. and Lactococcus ssp., and putative streptococcal x-Pro DPPs. The second activity was a putative serine-class arginine aminopeptidase (Sg- RAP) with some cysteine-class characteristics. It was found as a protein monomer of 70 kDa under denaturing conditions. Nested PCR cloning enabled the isolation of a 324 bp- long DNA fragment encoding the protein’s 108 amino acid N-terminus. Culture activity profiles and N-terminal sequence analysis indicated the release of this protein from the cell surface. -

Overall*,†,‡ † ‡ Life Sciences Institute, Department of Oral Biological and Medical Sciences, and Department of Biochemistry and Molecular Biology, University of British Columbia, Vancouver, British Columbia V6T 1Z4, Canada ABSTRACT: Proteases enzymatically hydrolyze peptide bonds in substrate proteins, resulting in a widespread, irreversible posttranslational modification of the protein’s structure and biological function. Often regarded as a mere degradative mechanism in destruction of proteins or turnover in maintaining physiological homeostasis, recent research in the field of degradomics has led to the recognition of two main yet unexpected concepts. First, that targeted, limited proteolytic cleavage events by a wide repertoire of proteases are pivotal regulators of most, if not all, physiological and pathological processes. Second, an unexpected in vivo abundance of stable cleaved proteins revealed pervasive, functionally relevant protein processing in normal and diseased tissuefrom 40 to 70% of proteins also occur in vivo as distinct stable proteoforms with undocumented N- or C- termini, meaning these proteoforms are stable functional cleavage products, most with unknown functional implications.
