Abstract:Rhodotorucine A is a peptidyl factor which induces mating tube formation in Rhodosporidiumtoruloides. The amino acid sequence of the factor was determined by Edman degradation and enzymatic hydrolysis. Rhodotorucine A was shown to contain a lipophilic amino acid, S-farnesyl cysteine, at C-terminus by proton magnetic resonance, mass spectrometry and chemical synthesis. We proposed the following structure for rhodotorucine A. H-Tyr-Pro-Glu-Ile-Ser-Trp-Thr-Arg-Asn-Gly-Cys(S-farnesyl)-OH
