Improved secretion of Candida antarctica lipase B with its native signal peptide in Pichia pastoris.

Secretion efficiency of the 85-amino acid Sacchromyces cerevisiae alpha signal peptide and the 25-amino acid Candida antarctica lipase B signal (nsB) peptide were compared. Three reporter proteins used for the study are C. antarctica lipase A (CalA), lipase B (CalB) and hGMCSF.
