We have determined a 17484 bp nucleotide sequence around the 39° region, located about 480 kb downstream from the zero position of the chromosome physical map. Among the 17 putative ORFs identified, and seem to correspond to and , encoding mannitol-specific phosphotransferase enzyme II and mannitol-1-phosphate dehydrogenase, respectively. seems to be another signal peptidase I gene () of . The putative products of six ORFs were similar to known proteins in data banks, namely a hypothetical 29-7 kDa protein of (Orf7), a lactam utilization protein (Orf8), the urea amidolyase of yeast (Orf12), the IcIR regulatory protein for ace of (Orf13), penicillin-binding protein 2 (Orf16) and aryl-alcohol dehydrogenase (Orf17). The amino acid sequence of Orf3 showed 34% identity with that of LeuC of , though they seem to be functionally different. The remaining seven ORFs did not show similarity to any known proteins.
