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。

Spectacular subjects' consumption of the commodity-image transforms them into individuals whose practical needs and choices apparently matter to the order of things, for the narratives of their personal existences assume wondrous qualities that identify them with the symbolico-cultural configurations of their world, while their sensual, idiosyncratic extensions of themselves into the imagistic being of the spectacle, a kingdom of needs and gratified desires, become a means to stamp the world with their expansive individualities, one of whose main qualities, also gifts of the system of appearances, is an expansive tendency that equates life with possibility.
