A functional pyc gene was isolated from Lactococcus lactis subsp. lactis C2
and was found to complement a Pyc defect in L, lactis KB4. The deduced lac
tococcal Pyc protein was highly homologous to Pyc sequences of other bacter
ia. The pyc gene was also detected in Lactococcus lactis subsp. cremoris an
d L. lactis subsp. lactis by. diacetylactis strains.
