Abstract

Mutants (car) isolated from Salmonella typhimurium were unable to utilize or ferment the following carbohydrates (all d-configuration): glucose, fructose, mannose, N-acetylglucosamine, sorbitol, mannitol, maltose, melibiose, and glycerol. The mutants did utilize galactose, glucose 6-phosphate, gluconic acid, glucuronic acid, pyruvate, and l-lactate. Biochemical analysis showed that there were two classes of mutants, each lacking one component of a phosphotransferase system. CarA mutants were deficient in enzyme I; carB lacked the phosphate carrier protein, HPr. Mapping experiments showed that the carA gene was located near pro; the carB gene mapped near purC.

摘要

从鼠伤寒沙门氏菌中分离出的突变体(car)无法利用或发酵以下碳水化合物(均为d-构型):葡萄糖、果糖、甘露糖、N-乙酰葡糖胺、山梨醇、甘露醇、麦芽糖、蜜二糖和甘油。这些突变体能够利用半乳糖、6-磷酸葡萄糖、葡萄糖酸、葡糖醛酸、丙酮酸和L-乳酸。生化分析表明存在两类突变体,每类都缺少磷酸转移酶系统的一个组分。CarA突变体缺乏酶I;carB缺少磷酸载体蛋白HPr。定位实验表明carA基因位于pro附近;carB基因定位于purC附近。
