K. Tokugawa et al., A MODEL SYSTEM FOR THE CONTINUOUS PRODUCTION OF A HETEROLOGOUS PROTEIN USING A NOVEL SECRETION PROMOTING FACTOR WHICH OPERATES IN ESCHERICHIA-COLI, Journal of biotechnology, 37(1), 1994, pp. 33-37
The 'PAS factor', whose gene has been cloned from a species of Vibrio,
is a novel protein secretion factor which is functional in Escherichi
a coli cells. To demonstrate that practical use of the PAS factor gene
is' possible, we have constructed a model secretion vector 'pAS23'. U
sing this system, beta-lactamase was produced and secreted into the me
dium of a continuous culture system, after optimization of culture con
ditions.
