J. Perezperez et al., DIFFERENT PRLA PROTEINS INCREASE THE EFFICIENCY OF PERIPLASMIC PRODUCTION OF HUMAN INTERLEUKIN-6 IN ESCHERICHIA-COLI, Journal of biotechnology, 49(1-3), 1996, pp. 245-247
The export efficiency of a fusion of the Escherichia coli preOmpA sign
al peptide to human interleukin-6 can be significantly raised by coexp
ressing three different prlA alleles of secY along with wild type secE
. The effect seems prlA-specific, as prlGl (a prl allele of secE) does
not affect the export of preOmpA-hIL-6. Coexpression of secD and secF
also stimulates the export of the fusion protein.
