摘要：

Arthrobacter sp. 1-3-1 and a coryneform rod bacterium, strain T-1-3-Y, which assimilate cyclo(Gly-Gly) and cyclo(Gly-L-Tyr) at high rates, respectively, were isolated from sell. Both bacteria exhibit diketopiperazine-hydrolyzing activity intracellularly in contrast to the extracellular cyclo(Gly-Gly) hydrolase reported previously. Arthrobacter sp. 1-3-1 shows a much broader substrate specificity than strain T-1-3-Y, indicating the diversity of diketopiperazine hydrolysis in nature.
