A gene coding for a peptidoglycan recognition peptide (PGRP) is cloned, a recombinant vector into which said gene is introduced is obtained, and a transformant transformed with said recombinant vector is cultivated, thereby producing the PGRP in large amounts at high purity.

Peptidoglycan recognition proteins and their production

A gene coding for a peptidoglysan recognition peptide (PGRP) is cloned, a recombinant vector into which said gene is introduced is obtained, and a transformant transformed with said recombinant vector is cultivated, thereby producing the PGRP in large amounts at high purity.
