Control of expression of LlaI restriction in Lactococcus lactis.

Molecular microbiology - 1 Mar 1998

O'Sullivan D J, Klaenhammer T R

Abstract excerpt

The plasmid encoded LlaI R/M system from Lactococcus lactis ssp. lactis consists of a bidomain methylase, with close evolutionary ties to type IIS methylases, and a trisubunit restriction complex. Both the methylase and restriction subunits are encoded on a polycistronic 6.9 kb operon. In this study, the 5' end of the llal 6.9 kb transcript was determined by primer extension analysis to be 254 bp upstream from...
