Signalling functions for sphingolipid long-chain bases in Saccharomyces cerevisiae.
Over the past several years, studies of sphingolipid functions in the baker's yeast Saccharomyces cerevisiae have revealed that the sphingoid LCBs (long-chain bases), dihydrosphingosine and PHS (phytosphingosine), are important signalling molecules or second messengers under heat stress and during non-stressed conditions. LCBs are now recognized as regulators of AGC-type protein kinase (where A...
متن کاملAn Improved Reagent for Mycobacterial Nitrate Reductase
A new crystalline reagent for nitrate reductase tests was compared with standard liquid reagents on 437 strains of mycobacteria. The results for isolates of Mycobacterium avium complex, Mycobacterium kansasii, Mycobacterium gordonae, Mycobacterium scrofulaceum, Mycobacterium fortuitum, and Mycobacterium chelonei agreed 100% with the expected results. Of the 177 Mycobacterium tuberculosis isolat...

متن کاملBiosynthesis of unsaturated sphingolipid bases by microsomal preparations from oysters.
A cell-free particulate preparation from oyster viscera incorporated [r4C]palmitate and [r4C]serine into the long chain base sphingadienine. Both double bonds of the product were shown to have the frans configuration. frans2-Hexadecenoic and frans-6-hexadecenoic acids were not effective in decreasing the incorporation of the radioactive label from palmitate, nor was label from palmitate incorpo...
متن کاملTrimethylsilylation of malonate ester enols.
Malonic acid silylatesreadily to yield the expected bis-trimethylsilyl (TMS) ester; this ester reacts further in the silylating mixture to yield a tris-TMS derivative, apparently through enolization of one of the ester groups. Methylmalonic and hydroxymalonic acids behave similarly. The methyl and ethyl esters of malonic acid also silylate once with some facility. Mass spectra of these derivati...
