Description

Metabolism of various sulfur compounds in Bacillus subtilis during growth and sporulation was investigated by use of tracer techniques, in an attempt to clarify the mechanism involved in the formation of cystine rich protein of the spore coat.<br> Methionine, homocysteine, cystathionine, cysteine and some inorganic sulfur compounds (sulfate, sulfite and thiosulfate) were utilized by this organism as sulfur sources for its growth and sporulation. Biosynthesis of methionine from sulfate during growth was more or less inhibited by the addition of cysteine, homocysteine or cystathionine to the culture.<br> It is suggested from these results that in Bacillus subtilis methionine is synthesized from sulfate through cysteine, cystathionine and homocysteine as is the case in Salmonella or Neurospora. The results also suggest that the metabolism of sulfur-containing amino acids in Bacillus subtilis is strongly regulated by methionine and homocysteine.
