To develop a functional phosphate-regulated promoter in Pichia pastoris, a phosphate-responsive gene, PHO89, which encodes a putative sodium (Na(+))-coupled phosphate symporter, was isolated. Sequencing analyses revealed a 1,731-bp open reading frame encoding a 576-amino-acid polypeptide with 12 putative transmembrane domains. The properties of the PHO89(More)
The gene encoding translation elongation factor 1-α from the yeast Pichia pastoris was cloned. The gene revealed an open reading frame of 1,380 bp with the potential to encode a polypeptide of 459 amino acids with a calculated mass of 50.1 kDa. The potential of the promoter (P TEF1 ) in P. pastoris was investigated with comparison to the(More)
BACKGROUND Pichia pastoris has been recognized as an effective host for recombinant protein production. A number of studies have been reported for improving this expression system. However, its physiology and cellular metabolism still remained largely uncharacterized. Thus, it is highly desirable to establish a systems biotechnological framework, in which a(More)
