pgsCA

pgsC and pgsA are two genes in pgsBCA operon. Protein PgsBCA is a membrane protein responsible for the synthesis of γ-PGA. Subunit PgsC is responsible for glutamic acid’s polymerization and subunit PgsA is responsible for the secretion of γ-PGA (showed in Figure 3).

Funtion of part pgsB and pgsCA were validated through fermentation experiment. Wild type Bacillus amyloliquefaciens NK-1 strain could produce 3-4g/L γ-PGA after 48 hours of fermentation. In previous work in our laboratory, we also tested heterologous expression of γ-PGA in E. coli. We constructed different expression vectors containing pgsBCA genes and transformed them separately into E.coli JM109. The average production of γ-PGA in E. coli JM109 is around 0.5g/L.
