Proline-tyrosine nuclear localization signals (PY-NLSs) are recognized and transported into the nucleus by human Karyopherin (Kap) beta2/Transportin and yeast Kap104p. Multipartite PY-NLSs are highly diverse in sequence and structure, share a common C-terminal R/H/KX2-5PY motif, and can be subdivided into hydrophobic and basic subclasses based on loose N-terminal sequence motifs. PY-NLS variabi...

Yeasts are eukaryotic microorganisms including 1,500 species. They are an important model organism in modern cell biology research, and are one of the most thoroughly researched eukaryotic microorganisms. Some yeast can find potential application in the field of bioremediation. In the present investigation the yeast samples were isolated on YPD medium from natural sources like ripened fruits, m...
