A gene, hmp, which encodes a ubiquitous protein homologous to hemoglobin was isolated among genes from Bacillus subtilis that are induced under anaerobic conditions. The hmp protein belongs to the family of two-domain flavohemoproteins, homologs of which have been isolated from various organisms such as Escherichia coli, Alcaligenes eutrophus, and(More)
The nucleotide sequence of the 20,535 base pairs of the 5' end of the srfA operon, containing the region required for competence development, was determined. This included the srfA promoter region, the first open reading frame, srfAA, encoding surfactin synthetase I and part of the second open reading frame, srfAB, encoding surfactin synthetase II. Three(More)
A mutation in any one of eight spoO genes of Bacillus subtilis blocks the process of spore formation at its earliest stage. To investigate how the products of the spoO genes may be involved in developmental gene expression, we fused the lacZ gene of E. coli to spoVG, a sporulation gene whose induction at the onset of sporulation is under spoO control. In(More)
Bacillus subtilis JH642 and a wild strain of B. subtilis called 22a both produce an antilisterial peptide that can be purified by anion-exchange and gel filtration chromatography. Amino acid analysis confirmed that the substance was the cyclic bacteriocin subtilosin. A mutant defective in production of the substance was isolated from a plasmid gene(More)
ATP-dependent proteases degrade denatured or misfolded proteins and are recruited for the controlled removal of proteins that block activation of regulatory pathways. Among the ATP-dependent proteases, those of the Clp family are particularly important for the growth and development of Bacillus subtilis. Proteolytic subunit ClpP, together with regulatory(More)
In this paper a novel approach to obstacle tracking in low-resolution range image sequences using template matching is proposed. Our tracking scheme takes into account particular problems with range data, normally not present in brightness imagery. The range images are spatially undersampled and due to poor target reflectiv-ity they include incomplete data.(More)
