(Submitter supplied) Transcriptomes of L. lactis MG1363ΔcelBΔptcCΔ0963 containing either an IS905 or a gfp integrated into llmg_1239 (pseudo_39) were compared to that of MG1363 with a Pcel (llmg_0186)up-mutation An integration of IS905 into a gene coding for a transcriptional repressor led to activation of the repressed gene cluster coding for a plant sugar utilization pathway. The strain is further characterized using DNA MicroArrays.

(Submitter supplied) pBL1 is a Lactococcus lactis theta-replicating 10.9-kbp plasmid that encodes the synthetic machinery of the bacteriocin Lcn972. In this work, the transcriptomes of exponentially growing L. lactis with and without pBL1 were compared. A discrete response was observed with a total of ten genes showing significantly changed expression. Up-regulation of the lactococcal oligopeptide uptake system (opp) was observed, likely linked to a higher nitrogen demand required for Lcn972 biosynthesis. more...

(Submitter supplied) Lactococcus lactis NZ9000 and its parent MG1363 are the most commonly used lactic acid bacteria for expression and physiological studies. We noted unexpected but significant differences in the growth behaviors of both strains. We sequenced the entire genomes of the original NZ9000 and MG1363 strains using an ultradeep sequencing strategy. The analysis of the L. lactis NZ9000 genome yielded 79 differences, mostly point mutations, with the annotated genome sequence of L. more...

(Submitter supplied) The human pathogen Streptococcus pneumoniae has the ability to use the carbon- and energy source cellobiose due to the presence of a cellobiose-utilizing gene cluster (cel locus) in its genome. This system is regulated by the cellobiose-dependent transcriptional activator CelR, which has been previously shown to contribute to pneumococcal virulence. To get a broader understanding of the response of S. more...

(Submitter supplied) CodY of Lactococcus lactis MG1363 is a transcriptional regulator that represses the expression of several genes encoding proteins of the proteolytic system. DNA microarray analysis, comparing the expression profiles of L. lactis MG1363 and an isogenic strain in which codY was mutated, was used to determine the CodY regulon. In peptide-rich medium and exponentially growing cells, where CodY exerts strong repressing activity, the expression of over 30 genes was significantly increased upon removal of codY. more...
