Bacillus subtilis is the best-characterized member of the Gram-positive bacteria. Its genome of 4,214,810 base pairs comprises 4,100 protein-coding genes. Of these protein-coding genes, 53% are represented once, while a quarter of the genome corresponds to several gene families that have been greatly expanded by gene duplication, the largest family containing 77 putative ATP-binding transport proteins. In addition, a large proportion of the genetic capacity is devoted to the utilization of a variety of carbon sources, including many plant-derived molecules. The identification of five signal peptidase genes, as well as several genes for components of the secretion apparatus, is important given the capacity of Bacillus strains to secrete large amounts of industrially important enzymes. Many of the genes are involved in the synthesis of secondary metabolites, including antibiotics, that are more typically associated with Streptomyces species. The genome contains at least ten prophages or remnants of prophages, indicating that bacteriophage infection has played an important evolutionary role in horizontal gene transfer, in particular in the propagation of bacterial pathogenesis.
        
Title: A new Bacillus subtilis gene, med, encodes a positive regulator of comK Ogura M, Ohshiro Y, Hirao S, Tanaka T Ref: Journal of Bacteriology, 179:6244, 1997 : PubMed
Bacillus subtilis degR, a positive regulator of the production of degradative enzymes, is negatively regulated by the competence transcription factor ComK which is overproduced in mecA null mutants. We used transposon Tn10 to search for a mutation that reduced the repression level of degR caused by a mecA mutation. A new gene exerting positive regulation on comK was obtained and designated med (suppressor of mecA effect on degR). Sequence determination, Northern analysis, and primer extension analyses revealed that the med gene contained an open reading frame (ORF) composed of 317 codons and was transcribed into an approximately 1,250-nucleotide mRNA together with its short downstream gene. The expression of comK is positively regulated by factors such as ComK itself, ComS (SrfA)-MecA, DegU, SinR, and AbrB. Quantitative analyses using comK'-'lacZ, srfA-lacZ, degU'-'lacZ, and sinR'-'lacZ fusions showed that disruption of med caused a significant decrease in comK expression in both mecA+ and mecA strains, while expression of srfA, sinR, and degU was not affected by the mutation. An epistatic analysis revealed that overproduction of ComK resulted in alteration of med expression, suggesting a regulatory loop between comK and med. Several possible mechanisms for positive regulation of comK by Med are discussed.
