Abstract

RizA is an L-amino-acid ligase from Bacillus subtilis that participates in the biosynthesis of rhizocticin, an oligopeptide antibiotic. The substrate-free form of RizA has been crystallized and the structure was solved at 2.8 Å resolution. The amino-acid-binding site appears to be capable of accommodating multiple amino acids, consistent with previous biochemical studies.

摘要

RizA是一种来自枯草芽孢杆菌的L-氨基酸连接酶,参与寡肽抗生素根霉素的生物合成。RizA的无底物形式已被结晶,并以2.8 Å的分辨率解析了其结构。氨基酸结合位点似乎能够容纳多个氨基酸,这与之前的生化研究结果一致。
