title: Cloning and sequencing of the leu C and npr M genes and a putative spo IV gene from Bacillus megaterium DSM319.
abstract: The leuC gene, encoding 3-isopropylmalate dehydrogenase, the nprM gene (neutral protease) and a sporulation gene coding for a putative spoIV protein (spoIV) from Bacillus megaterium DSM 319 were cloned and the nucleotide sequences were determined. The leuC gene is 1101 bp in length, preceded by a ribosome binding site; no promoter consensus sequence could be found. The nucleotide sequence from nprM when compared to the recently published gene from B. megaterium ATCC 14581 exhibited only a 17-base pair deviation. From a sporulation mutant isolated after transposon-mutagenesis with transposon Tn917 the insertion site of the transposon was cloned and adjacent chromosomal fragments were characterized. An open reading frame that encodes for a putative spo protein of 247 amino-acid residues was identified.
