Phylogenetic Distribution of Fungal Sterols

Phylogenetic Distribution of Fungal Sterols

BACKGROUND Ergosterol has been considered the "fungal sterol" for almost 125 years; however, additional sterol data superimposed on a recent molecular phylogeny of kingdom Fungi reveals a different and more complex situation. METHODOLOGY/PRINCIPAL FINDINGS The interpretation of sterol distribution data in a modern phylogenetic context indicates that there is a clear trend from cholesterol and...

Phylogenetic analysis of fungal centromere H3 proteins.

Centromere H3 proteins (CenH3's) are variants of histone H3 specialized for packaging centromere DNA. Unlike canonical H3, which is among the most conserved of eukaryotic proteins, CenH3's are rapidly evolving, raising questions about orthology and conservation of function across species. To gain insight on CenH3 evolution and function, a phylogenetic analysis was undertaken on CenH3 proteins d...

Transbilayer distribution of sterols in mycoplasma membranes: a review.

The polyene antibiotic, filipin, binds to 3 beta-hydroxysterols. The initial rate of filipin-sterol association, monitored in a stopped-flow spectrophotometer, was first order in each reacting partner. The ratio of rate constants in intact mycoplasma cells relative to isolated, unsealed membranes provides an estimate of sterol distribution in the membrane bilayer. Cholesterol is distributed sym...

Plasma clearance and tissue distribution of liposomes containing different sterols.

was precipitated (Kane et al., 1975) with 1,1,3,3-tetramethylurea, extracted with chloroform/methanol (1 : 1, v/v), washed with ether, and dried under N2. Amino acid analysis of this protein corresponded to that of apolipoprotein B, as did its electrophoretic mobility on urea/polyacrylamide-gel electrophoresis. Its specific radioactivity was obtained by radioactivity counting and protein determ...
