Bacillus subtilis extracellular nuclease production associated with the spoOH sporulation locus.
A number of nuclease-deficient mutants of Bacillus subtilis were isolated and found to be concurrently asporogenous. The nuclease-deficient phenotype appeared to be associated with the spoOH sporulation locus. Spontaneously occurring sporogenous revertants concomitantly recovered the ability to produce extracellular nuclease activity. The position of the ncl mutation was determined using transformation and PBS1 transduction and found to map in the same site as spoOH. The map order of ncl and markers in the vicinity was determined to be purA-cysA-ncl(spoOH)-strA.
