DIHYDROLIPOAMIDE DEHYDROGENASE OF GLYCINE DECARBOXYLASE FROM PISUM SATIVUM

Overview

The glycine decarboxylase complex consists of four different component, enzymes (P-, H-, T- and L-proteins). The 14-kDa lipoamide-containing, H-protein plays a pivotal role in the complete sequence of reactions as, its prosthetic group (lipoic acid) interacts successively with the three, other components of the complex and undergoes a cycle of reductive, methylamination, methylamine transfer and electron transfer. With the aim, to understand the interaction between the H-protein and its different, partners, we have previously determined the crystal structure of the, oxidized and methylaminated forms of the H-protein. In the present study, we have crystallized the H-protein in its reduced state and the L-protein, (lipoamide dehydrogenase or dihydrolipoamide dehydrogenase). The L-protein, ... [(full description)]
