Abstract


Secretion-associated and Ras-related protein (Sar1p) plays an essential role during the protein transport from the endoplasmic reticulum to the Golgi apparatus. The cDNA sequence of the Sar1 gene has been identified and characterized from the human yeast pathogen, Candida albicans. This cDNA encodes a protein of 190 amino acids, which shares a 78% sequence identity with Saccharomyces cerevisiae Sar1p and contains the conserved GTP-binding motifs of the small GTPase superfamily. Complementation studies confirmed that this cDNA encodes the functional homologue of ScSar1p. The recombinant C. albicans Sar1p exhibits GTP-binding activity in vitro that was abolished by deletion of one of the three GTP-binding motifs.
