Study on the Crystallization Process of Labeled GL-7-ACA Acylase CA130 Complex 7β-bromoacetyl amino cephalosporanic acid (BA-7-ACA), an analog of glutaryl-7-amino cephalosporanic acid (GL-7-ACA), can inhibit and specifically alkylate GL-7-ACA acylase (CA130) from Pseudomonas sp. 130, forming a carbon-carbon bond between BA-7-ACA and the C-2 on indole ring of Trp-β4 residue of CA130.Here we reported that BA-7-ACA labeled CA130 (BA-C130) could self-catalyze the hydrolysis of BA-7-ACA during crystallization process. The hydrolysis was confirmed to be a reaction analogous to the one of GL-7-ACA by comparative MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight) spectrometry analysis.

二、GL-7-AcA酰化酶CA130标记复合物的结晶过程研究溴乙酰氨基头孢烷酸（7β-bromoacetyl amino cephalosporanic acid，BA-7-ACA）作为戊二酰-7-氨基头孢烷酸（GL-7-ACA）的类似物，不仅能够抑制GL-7-ACA酰化酶CA130的活力，而且能通过在BA-7-ACA和CA130的β亚基第四位色氨酸吲哚环二位碳原子之间形成碳-碳共价键而将CA130特异的烷基化。
