Current protocols in cell biology, Chapter 7, Unit 7-Unit 7 (2008-01-30)
This unit provides protocols for prenylation and carboxy-methylation of proteins in cultured cells. These modifications often accompany fatty acid acylation. Cultured cells can be labeled biosynthetically using radiolabeled mevalonate, a precursor, to label intermediates that are incorporated as prenoids--e.g., farnesyl

A comparative study of four peptidomimetics of the sequence Phe-Met-Arg-Phe-amide (FMRFa) was performed to compare the conformational bias caused by trans-2,3-methanomethionine and alpha-methylmethionine stereoisomers. The specific compounds studied were {(2S,3S)-cyclo-M} RFa, F{(2R,3R)-cyclo-M} RFa, F{(S)-alpha-Mem} RFa, and F{(R)-alpha-MeM} RFa. Molecular simulations

Methionine, alpha-methylmethionine and S-methylcysteine radical cations have been formed by oxidative dissociations of [CuII(M)(CH3CN)2]*2+ complexes. The radical cations M*+ were trapped, and CID spectra (MS3) of these ions are presented. Fragmentations of the methionine and S-methylcysteine radical cations, initiated by
