Abstract excerpt
Lactococcus lactis subsp. cremoris P8-2-47 contains an X-prolyl dipeptidyl aminopeptidase (X-PDAP; EC 3.4.14.5). A mixed-oligonucleotide probe prepared on the basis of the N-terminal amino acid sequence of the purified protein was made and used to screen a partial chromosomal DNA bank in Escherichia coli. A partial XbaI fragment cloned in pUC18 specified X-PDAP activity in E. coli clones. The fragment was also...
