Enzymatic Assay of Achromopeptidase
在测定羧肽酶A活性时,使用马尿酸-L-苯丙氨酸在254nm处进行连续分光光度法测定。羧肽酶A水解C末端残基上的肽键。
Objective: To standardize a procedure for the assay of Carboxypeptidase A
To measure chloramphenicol acetyltransferase activity, this procedure uses DTNB and coenzyme A. The reaction of DTNB with the –SH group on CoA results in a colorimetric increase at 412 nm.
