Screening was carried out for microorganisms able to produce N-(l-alpha-l-aspartyl)-l-phenylalanine methyl ester [APM] from l-isoasparagine and l-phenylalanine methyl ester hydrochloride. Of the 422 strains examined, 44 strains belonging to the family Enterobacteriaceae were found to produce APM. The enzyme catalyzing

1. Programmed cell death proceeds by an unknown mechanism which results in characteristic morphological changes known as apoptosis. 2. We have proposed that, in hormone-induced apoptosis, cell death may be the result of an attack of cells destined to die
