Temperature-sensitive mutant alleles of the GCS1 gene were created by a mutagenic polymerase chain reaction (PCR) “gap-repair” procedure. 24 A “gapped” plasmid (pPPL18) was first constructed by cloning the 5′ and 3′ noncoding … WebTryptophan synthesis in E. coli is highly regulated by a complex set of feedback mechanisms. By transducing each mutation one at a time, researchers combined a long list of alterations to these mechanisms within a single strain, thus creating a tryptophan overproducer (Aiba et al., 1980; Shio, 1986).
