BotH
Comment
The bottromycin epimerase BotH defines a group of atypical alpha/beta-hydrolase-fold enzymes. BotH is a peptide epimerase responsible for the post-translational epimerization of L-Asp to D-Asp during bottromycin biosynthesis. D-amino acids endow peptides with diverse, desirable properties, but the post-translational and site-specific epimerization of L-amino acids into their D-counterparts is rare and chemically challenging. The activity does not rely on a catalytic triad. No conservation of Ser (replaced by Phe) nor His or Asp. The residues Phe110 and Val41 seem important in hydrogen bonding to substrate
