Molecular Cloning of the Gene Encoding a Highly Expressed Protein in SFL1 Gene-Disrupted Flocculating Yeast

抄録

We identified a yeast gene encoding Flocculent Specific Protein (FSP) produced excessively in the SFL1 gene-disrupted flocculent strain. The sequenced gene encodes a 430 amino acid protein and is mainly composed of multiple repeats of Ser-Asn-Asn-X-Asp-Ser-Tyr-Gly. The FSP gene disruption of the flocculent strain decreased the degree of flocculation, so FSP may be one factor concerned with yeast flocculation. A gene database search indicated that the FSP gene is identical with the DDR48 gene.
