Localization of subunit C (Vma5p) in the yeast vacuolar ATPase by immuno electron microscopy.

abstract：:Using a radioimmunoassay for the peptide sequence Arg-Phe-NH2 (RFamide), a novel peptide has been purified from acetic acid extracts of the sea anemone Anthopleura elegantissima. This peptide has the structure less than Glu-Gly-Leu-Arg-Trp-NH2, and was named Antho-RWamide II. Antho-RWamide II is a neuropeptide. Its st...
