| Note(s): | Based on the one-round PCR product method, a novel site-directed mutagenesis method, it was determined that an srlA-driven expression system is a tool applicable for strong expression of foreign genes under cultivation conditions in LB medium without induction Nakamura M, Aihara J, Hoshida H, Akada R,2018 In addition, it was determined that the sequence adjacent to the start codon of the srlA gene is essential for high expression and that its promoter region is 100 bp. srlAp is a constitutive promoter in LB medium, and it is a sorbitol-enhanceable and glucose-, fructose-, galactose-, mannose-, xylose-, and arabinose- repressible promoter Nakamura M, Aihara J, Hoshida H, Akada R,2018 | |||||||||
