ASPARTATE BETA-SEMIALDEHYDE DEHYDROGENASE FROM ESCHERICHIA COLI
Overview
Aspartate beta-semialdehyde dehydrogenase (ASADH) lies at the first branch, point in an essential aspartic biosynthetic pathway found in bacteria, fungi and the higher plants. Mutations in the asd gene encoding for ASADH, that produce an inactive enzyme are lethal, which suggests that ASADH may, be an effective target for antibacterial, herbicidal and fungicidal, agents.We have solved the crystal structure of the Escherichia coli enzyme, to 2.5 A resolution using single isomorphous replacement and 3-fold, non-crystallographic symmetry. Each monomer has an N-terminal, nucleotide-binding domain and a dimerisation domain. The presence of an, essential cysteine locates the active site in a cleft between the two, domains. The functional dimer has the appearance of a butterfly, with the, ... [(full description)]
