The proton-decoupled 15N Fourier transform nuclear magnetic resonance (NMR) spectra of 15N-enriched Escherichia coli, Bacillus licheniformis, baker's yeast, and Friend leukemic cells were obtained. The 15N NMR spectra of whole cells displayed 15N resonances originating from (i) protein backbones with lysine, arginine, and histidine side chains, (ii) ribonucleic acids, (iii) peptidoglycan, and (...

With the exceptions of Bacillus cereus and Bacillus anthracis, Bacillus species are generally perceived to be inconsequential. However, the relevance of other Bacillus species as food poisoning organisms and etiological agents in nongastrointestinal infections is being increasingly recognized. Eleven Bacillus species isolated from veterinary samples associated with severe nongastrointestinal in...

The membrane penicillinase (penicillin amido-beta-lactamhydrolase, EC 3.5.2.6) from Bacillus licheniformis, the Semliki Forest virus spike proteins, and the Sendai virus glycoproteins have each been isolated as soluble protein aggregates that are virtually free of lipid and detergent. The sedimentation coefficients of the complexes were 18 S, 29 S, and 43 S, respectively. Mixed aggregates conta...
