THE STRUCTURE OF PHOSPHOSERINE AMINOTRANSFERASE FROM E. COLI IN COMPLEX WITH ALPHA-METHYL-L-GLUTAMATE

Overview

Phosphoserine aminotransferase (PSAT; EC 2.6.1.52), a member of subgroup, IV of the aminotransferases, catalyses the conversion of, 3-phosphohydroxypyruvate to l-phosphoserine. The crystal structure of PSAT, from Escherichia coli has been solved in space group P212121 using MIRAS, phases in combination with density modification and was refined to an, R-factor of 17.5% (Rfree=20.1 %) at 2.3 A resolution. In addition, the, structure of PSAT in complex with alpha-methyl-l-glutamate (AMG) has been, refined to an R-factor of 18.5% (Rfree=25.1%) at 2.8 A resolution. Each, subunit (361 residues) of the PSAT homodimer is composed of a large, pyridoxal-5'-phosphate binding domain (residues 16-268), consisting of a, seven-stranded mainly parallel beta-sheet, two additional beta-strands and, seven ...
