A peptidase from Escherichia coli B has been prepared in a highly pure form and characterized with respect to its substrate specificity, requirements for activity, size and subunit structure. This enzyme preferentially catalyzes the hydrolysis of certain methionyl dipeptides and for this reason is referred to as dipeptidase M. Of the substrates tested with the homogeneous enzyme methionylalanin...
The stability of DA-1131 to renal dipeptidase (RDPase) (EC 3.4.13.19) was compared with that of imipenem and meropenem by V(max)/K(m) ratios as an index of the enzyme's preference for substrates. Our results showed a decreasing order of imipenem (6.24), meropenem (2.41), and DA-1131 (1.39). The biochemical evaluation of DA-1131 as the least preferred substrate of RDPase suggests its potential u...
The somatic angiotensin I-converting enzyme (sACE; peptidyl-dipeptidase A; EC 3.4.15.1) was isolated from pig lung and purified to homogeneity. The purified enzyme has a molecular mass of about 180 kDa. Upon proteolytic cleavage, two approximately 90 kDa fragments were obtained and identified by amino-terminal sequence analysis as the N- and C-domains of sACE. Both purified domains were shown t...
