Abstract
A study was made of the effect of RcsA and RcsB on the Vibrio fischeri lux expression in Escherichia coli. RcsA suppressed the LuxR activity and thereby inhibited expression of the lux genes coding for luciferase and reductase. In osmotic shock, RcsA-RcsB activated lux expression and, consequently, bioluminescence of E. coli cells in the early log phase.
摘要
研究了RcsA和RcsB对费氏弧菌lux在大肠杆菌中表达的影响。RcsA抑制LuxR活性，从而抑制编码荧光素酶和还原酶的lux基因的表达。在渗透压休克中，RcsA - RcsB激活lux表达，进而激活对数早期大肠杆菌细胞的生物发光。
