Varieties of pyruvate carboxylase [pyruvate: CO2 ligase (ADP-forming), EC 6.4.1.1] obtained from the livers of several species of vertebrates, including humans, all show the same basic structure. They are composed of large polypeptide chains of molecular weights ranging from 1.2 to 1.3 X 10(5) for the different varieties of the enzyme. The native form of(More)
A photolabile reagent, p-azidobenzoyl-CoA, has been synthesized and tested as a photoaffinity label for acyl-CoA:glycine N-acyltransferase (EC 2.3.1.13) from beef liver. p-Azidobenzoyl-CoA is an active-site-directed reagent for this N-acyltransferase, since it is an alternate substrate (Km = 26 micronM, when [glycine] = 100 mM).
