Expression And Characterization Of Ecm14, A Metallocarboxypeptidase From Saccharomyces Cerevisiae, Matthew James Schott
Expression And Characterization Of Ecm14, A Metallocarboxypeptidase From Saccharomyces Cerevisiae, Matthew James Schott
Master's Theses
Metallocarboxypeptidases are found in most organisms and function in the digestion and maturation of proteins. Ecm14 is a putative metallocarboxypeptidase found in the yeast Saccharomyces cerevisiae vacuole. The function of Ecm14 as an enzyme has been unclear due to the presence of active site amino acids not typically found in metallocarboxypeptidases, suggesting either no enzymatic activity or a unique mechanism. In order to investigate the enzymatic mechanism of Ecm14, expression of histidine-tagged Ecm14 protein was attempted in human HEK293T cell culture, S. cerevisiae, and baculovirus expression systems. No expression was detected in HEK293T cells in preliminary experiments. Expression in the …
