Expression of cellulase genes in Rhodobacter capsulatus by use of plasmid expression vectors.

PMCID: PMC212932  PMID: 3090019

Abstract

Broad-host-range plasmid vectors were constructed for expression of heterologous genes in the photosynthetic bacterium Rhodobacter capsulatus. These plasmids utilize an RK2-derived replicon for maintenance and conjugative transfer and the R. capsulatus rxcA promoter to obtain transcription of genes within appropriately positioned DNA fragments. The expression vectors were used to obtain synthesis of endoglucanase and exoglucanase in R. capsulatus from cellulase genes present on exogenously derived DNA fragments. The cellulase genes were expressed either by use of their native translation initiation signals or by in-frame fusion with the rxcA B870 beta gene translation initiation signals to form a hybrid protein. The level of cellulase gene expression was found to be modulated in response to the extent of aeration of plasmid host cultures.
