Abstract
A mutant requiring isoleucine and valine for growth, because of the absence of acetolactate synthase activity, has been isolated. At least one of three different genes (ilvG, ilvB, ilvI) is required for the expression of acetolactate synthase activity, thus suggesting the presence of three different acetolactate synthase isoenzymes.
摘要
由于缺乏乙酰乳酸合酶活性，已分离出一种生长需要异亮氨酸和缬氨酸的突变体。乙酰乳酸合酶活性的表达需要三个不同基因（ilvG、ilvB、ilvI）中的至少一个，因此表明存在三种不同的乙酰乳酸合酶同工酶。
