A pleiotropic mutation at the ssd locus was mapped at 86 min near rha. A mutation at the ssd locus resulted in elevated L-serine deaminase activity, inability to grow with succinate as the carbon source, and inability to grow anaerobic conditions.
ssd位点的一个多效性突变被定位在靠近rha的86分钟处。ssd位点的突变导致L-丝氨酸脱氨酶活性升高,无法以琥珀酸盐作为碳源生长,并且在厌氧条件下无法生长。
