A low-temperature protein expression system is useful for the production of thermolabile proteins. We previously developed a system that enables constitutive protein production at low temperatures, using the psychrotrophic bacteriumShewanella livingstonensisAc10 as the host. To increase the utility of this system, in the present study, we introduced a repressible promoter of thetrpoperon of this bacterium into the system. When ß-lactamase was produced under the control of this promoter at 18°C and 4°C, the yields were 75 and 33 mg/L-culture, respectively, in the absence ofl-Trp, and the yields were decreased by 72% and 77%, respectively, in the presence ofl-Trp. We also found that 3-indoleacrylic acid, a competitive inhibitor of theEscherichia coli trprepressor, increased the expression of the reporter gene. This repressible gene expression system would be useful for regulatable recombinant protein production at low temperatures.
