Notes

Method of Mutagenesis: Log-phase cultures of strain GM 1 were treated with Alkylating agent (N-methyl-N-nitro-nitrosoguanidine)[4]


Phenotype Observed: Mutants were tested for S-adenosylmethionine methyltransferase activity by measuring the levels of DNA-cytosine (S-adenosylmethionine and DNA-adenine. The mutants showed reduced or absent activity. Also, deficient in methylcytosine in DNA. [4]
