+ | == Publication Abstract from PubMed == | ||
+ | In bacteria and plants, dihydrodipicolinate synthase (DHDPS) plays a key role in the (S)-lysine biosynthesis pathway. DHDPS catalyzes the first step of the condensation of (S)-aspartate-beta-semialdehyde and pyruvate to form an unstable compound, (4S)-4-hydroxy-2,3,4,5-tetrahydro-(2S)-dipicolinic acid. The activity of DHDPS is allosterically regulated by (S)-lysine, a feedback inhibitor. The crystal structure of DHDPS from Methanocaldococcus jannaschii (MjDHDPS) was solved by the molecular-replacement method and was refined to 2.2 A resolution. The structure revealed that MjDHDPS forms a functional homotetramer, as also observed in Escherichia coli DHDPS, Thermotoga maritima DHDPS and Bacillus anthracis DHDPS. The binding-site region of MjDHDPS is essentially similar to those found in other known DHDPS structures. | ||
