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.

The effect of N-phosphoamino acids on plant cells'membrane permeability was investigated by osmotic method. It was found that in all N-phosphoamino acids, only some phosphoryl polar amino acids such as DIPPSer, DIPPThr, DIPPHis, DIPPAsp, DIPPGlu, DIPPAsn and free serine, threonine could increase the water permeability in plant cell membrane. For example, after 20min. treatment by 1. 5mM DIPPSer, the deplasmolysis time of onion cells was shortened 50%.

The kinetics of reconstitution of apoacylase with either 〓 or 〓 and the inactivation of the 〓 reconstituted enzyme by 1, 10-phenanthroline has been studied by following the substrate reaction continuously in presence of the metal ion or OP respectively. Although the native 〓-containing and the 〓-reconstituted enzymes have closely similar Michaelis constants and maximal velocities, the kinetics for both the inactivation by OP and the reconstitution of the apoenzyme with the metal ions differs considerably.
