The Bacillus subtilis ureABC operon encodes homologs of the three subunits of urease enzymes of the family Enterobacteriaceae. Disruption of ureC prevented utilization of urea as a nitrogen source and resulted in a partial growth defect in minimal medium containing limiting amounts of arginine or allantoin as the sole nitrogen source.
枯草芽孢杆菌ureABC操纵子编码肠杆菌科脲酶三个亚基的同源物。ureC的破坏阻止了利用尿素作为氮源,并导致在含有有限量精氨酸或尿囊素作为唯一氮源的基本培养基中出现部分生长缺陷。
