Research Abstract |
We searched for a novel L-amino acid ligase (Lal) possessing the activity toward acidic amino acids from a microorganism producing peptide antibiotics. A novel ligase that seemed to be involved in the biosynthesis of the antibiotics was obtained by enzyme purification and gene manipulation, but the search of the Lal showing the activity toward acidic amino acids has been under examination.
