Ligands: XVE Related: 3oqv Activity: Cyclo(L-leucyl-L-phenylalanyl) synthase, with EC number 2.3.2.20 Resources: FirstGlance, OCA, RCSB, PDBsum Function [CLPS_STRNR] Involved in the biosynthesis of albonoursin (cyclo[(alpha,beta-dehydro-Phe)-(alpha,beta-dehydro-Leu)]), an antibacterial peptide. It uses activated amino acids in the form of aminoacyl-tRNAs (aa-tRNAs) as substrates to catalyze the ATP-independent formation of cyclodipeptides which are intermediates in diketopiperazine (DKP) biosynthetic pathways. Catalyzes the formation of cyclo(L-Phe-L-Leu) (cFL) as major products from L-L-phenylalanyl-tRNA(Phe) and L-leucyl-tRNA(Leu). AlbC can also incorporate various nonpolar residues, such as L-phenylalanine, L-leucine, L-tyrosine and L-methionine, and to a much lesser extent L-alanine and L-valine, into cyclodipeptides. Indeed, ten possible cyclodipeptides composed of L-phenylalanine, L-leucine, L-tyrosine and L-methionine are all synthesized to detectable amounts by AlbC.
