Method for secreting and producing proteins

摘要

Provided is a method for secreting and producing polymeric proteins which exploits novel techniques for improving the polymeric protein secretion and production capabilities of coryneform bacteria. Polymeric proteins are secreted and produced using, as expression hosts, coryneform bacteria which have polymeric protein secretion and production capabilities, and which have been modified so as to have improved expression of genes for coding metallopeptidase.
