Abstract

l-Amino acid ligase catalyzes dipeptide synthesis from unprotected l-amino acids in an ATP-dependent manner. We recently identified a new member of l-amino acid ligase, the plu1440 protein, from Photorhabdus luminescens subsp. laumondii TT01 by in silico analysis. This protein was found to synthesize dipeptides containing l-asparagine at the N-terminus, which is a novel substrate specificity.
