β¦ Synopsis
A thermosensitive mutation pt8I1 in the gene coding for the Enzyme I of the PEP-phosphotransferase system pathway has been isolated. The mutant enzyme was shown to be sensitive to high temperature, but this effect is dependent on the ionic strength. The ptsI1 mutation was shown to belong to the previously described ctr locus. Following Lin (1970) it is proposed to retain the symbole ptsI for this locus.

The gene-enzyme relationship has been established for most of the steps of the purine de novo biosynthetic pathway in Bacillus subtilis. The synthesis of inosine monophosphate (IMP) involves ten steps, and the branching from IMP to AMP and to guanosine monophosphate (GMP) synthesis both require two
A gene coding for a modifying DNA-methyltransferase which methylates the central C in the BsuR recognition sequence 5'GGCC was identified in the genome of the temperate Bacillus subtilis phage SPfi. This gene is expressed only after induction of the prophage by either mitomycin C or UV. The presence
