Isolation of N-(2,6-diamino-6-hydroxymethylpimelyl)-l-alanine from Micromonospora chalcea.

Abstract
A novel dipeptide, N-(2, 6-diamino-6-hydroxymethylpimelyl)-L-alanine, was isolated from the culture broth of a microorganism identified as Micromonospora chalcea. The dipeptide exhibits antimicrobial activity against Escherichia coli on a synthetic medium, and the activity is synergistically enhanced by several cell wall synthesis-inhibitors.
