Expression vectors and promoters for heterologous gene expression.

摘要

A vector comprising a promoter can be operably linked to a gene encoding a heterologous protein, wherein the promoter induces expression of any operably linked heterologous protein, in the presence of nucleotides, which may or not said nucleotide phosphate group and wherein the promoter sequence is a xapA promoter, which comprises ribosomal binding site having the following sequence: AGGAGG xxxxx AGGAGG xxxxxx or AGGAGA xxxxx or AGGAGA xxxxxx or
