Abstract |
In order to identify the protein(s) secreted into culture medium by the soo1-1/ret1-1 mutation of Saccharomyces cerevisiae, proteins from the culture medium of cells grown at permissive (28^oC) and non-permissive temperatures (37^oC), were analyzed. Comparison of protein bands separated by SDS-PAGE identified a prominent band of 47-kDa band from a mutant grown at 37^oC. N-terminal amino acid sequencing of this 47-kDa protein showed high identity with enolases 1 and 2. Western blot analysis revealed that most of the cell wall-bound enolase was released into the culture medium of the mutant grown at 37^oC, some of which were separated as those with lower molecular weights. Our results, presented here, indicate the impairment of cell wall enolase biogenesis and assembly by the soo1-1/ret1-1 mutation of S. cerevisiae. |
