title: Translation elongation factor 1-alpha gene from Pichia pastoris: molecular cloning, sequence, and use of its promoter.
abstract: The gene encoding translation elongation factor 1-alpha 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 glyceraldehyde-3-phosphate dehydrogenase promoter (P (GAP)) by using a bacterial lipase gene as a reporter gene. P (TEF1) demonstrated a tighter growth-associated expression mode, improved functioning in the presence of high glucose concentrations, and promoter activities that yielded recombinant protein at levels similar to or in one case greater than P (GAP). The sequence of the gene was deposited in GenBank under accession no. EF014948.
