A gene for the constitutive ribosephosphate isomerase (rpiA) is highly cotransducible with serA at 56.2 min on the genetic linkage map of Escherichia coli K-12. Suppression of ribosephosphate isomerase A-negative mutants can occur by a regulator gene mutation permitting constitutive synthesis of the normally inducible ribosephosphate isomerase B.
在大肠杆菌K-12的遗传连锁图谱上,组成型核糖磷酸异构酶(rpiA)基因在56.2分钟处与serA基因高度共转导。核糖磷酸异构酶A阴性突变体的抑制可通过调节基因突变发生,该突变允许组成型合成通常可诱导的核糖磷酸异构酶B。
