Abstract
The aspartase (L-asparatate ammonia-lyase, EC. 4.3.I.I) structural gene, aspA, was mapped by two-factor and three-factor transductional crosses using phage PI. Cotransduction frequencies between aspA and other markers were: ampA (69%); frdA (48 TO 67%) mel (35%); purA (17%); fdp (I-6%). The sequence of markers within the corresponding segment (91 to 95 min) of the Escherichia coli linkage map was shown to be mel-aspA-ampA-frdA-purA-fdp.
摘要
天冬氨酸酶（L-天冬氨酸解氨酶，EC. 4.3.1.1）结构基因aspA，通过使用噬菌体P1的双因子和三因子转导杂交进行定位。aspA与其他标记之间的共转导频率为：ampA（69%）；frdA（48%至67%）；mel（35%）；purA（17%）；fdp（1%至6%）。大肠杆菌连锁图谱相应区段（91至95分钟）内标记的顺序显示为mel-aspA-ampA-frdA-purA-fdp。
