Two glucosamine (GCA)-requiring mutants have been isolated which grow on glucose minimal or nutrient sporulation medium only in the presence of either GCA or acetyl-GCA. They lack the l-glutamine-d-fructose-6-phosphate aminotransferase (EC 2.6.1.13), which is repressible by GCA and whose activity in the standard strain decreases after cessation of growth. But the mutants can grow on GCA as sole carbon and ammonia source, because GCA induces the synthesis of 2-amino-2-deoxy-d-glucose-6-phosphate… CONTINUE READING
