PSEUDOMONAS LIPASE COMPLEXED WITH RC-(RP, SP)-DIBUTYLCARBAMOYLGLYCERO-3-O-BUTYLPHOSPHONATE
Overview
To investigate the enantioselectivity of Pseudomonas cepacia lipase, inhibition studies were performed with Sc- and, Rc-(Rp,Sp)-1,2-dialkylcarbamoylglycero-3-O-p-nitrophenyl alkylphosphonates, of different alkyl chain lengths. P. cepacia lipase was most rapidly, inactivated by Rc-(Rp,Sp)-1,2-dioctylcarbamoylglycero-3-O-p-nitrophenyl, octylphosphonate (Rc-trioctyl) with an inactivation half-time of 75 min, while that for the, Sc-(Rp,Sp)-1,2-dioctylcarbamoylglycero-3-O-p-nitrophenyl octyl-phosphonate, (Sc-trioctyl) compound was 530 min. X-ray structures were obtained of P., cepacia lipase after reaction with Rc-trioctyl to 0.29-nm resolution at pH, 4 and covalently modified with, Rc-(Rp,Sp)-1,2-dibutylcarbamoylglycero-3-O-p-nitrophenyl butyl-phosphonate, (Rc-tributyl) to 0.175-nm resolution ...
