Two different expression vectors were constructed to investigate two signal peptides on secretion of Geobacillus thermoleovorans IT-08 -L-arabinofuranosidase (AbfA) in Saccharomyces cerevisiae. They were designed to direct the secretion of AbfA by the aid of one of the following signal peptides, the F signal peptide in the plasmid YEpFLAG1-Af and HM-1 signal peptide in the plasmid pYHM1-Af. Although some successful results have been reported in proteins secretion with F leader sequence, in this
