Abstract
The gene for protein A from Staphylococcus aureus was cloned into pBR322 in Escherichia coli. An immunoassay was used to detect production of the protein. Protein A produced in E. coli was found in the periplasmic space and was purified and concentrated by IgG-Sepharose affinity chromatography. DNA sequence assay of the gene revealed a region with the general features of a prokaryotic signal peptide and a fifth structural region homologous to the four repetitive regions found earlier by amino acid sequence determination of the mature protein. Upstream from the structural gene there is a possible promoter region and a ribosomal binding sequence typical of gram-positive bacteria. The initiation codon is TTG.
