A novel technique for improving ability for secretory production of a multimeric protein of a coryneform bacterium is provided, and thereby a method for secretory production of a multimeric protein is provided. A multimeric protein is produced by secretory production utilizing a coryneform bacterium having an ability to produce a multimeric protein by secretory production and modified so that expression of a gene coding for a metallopeptidase is increased as an expression host.

Method for secretory production of protein

A method for secretory production of a heterologous protein is provided by developing a novel technique for improving ability of a coryneform bacterium to produce a heterologous protein by secretory production. By utilizing a coryneform bacterium having an ability to produce a heterologous protein by secretory production which has been modified so that the activity of a penicillin-binding protein is reduced and in which the activity of a cell surface layer protein has been reduced as an expression host, a heterologous protein is produced by secretory production.
