Fatty acylation of proteins during development of sea urchin embryos.
Developing embryos of the sea urchin, Strongylocentrotus purpuratus, incorporate [3H]palmitic acid into at least 20 proteins. The [3H]palmitic acid associated with these proteins is released by alkaline hydrolysis or by treatment with hydroxylamine but not by extensive extraction with chloroform:methanol, indicating that the fatty acids are covalently attached to protein. The finding that the f...
متن کاملCell-free fatty acid acylation of Semliki Forest viral polypeptides with microsomal membranes from eukaryotic cells.
Using [14C]palmitoyl-CoA as donor and deacylated (fatty acid-free) structural proteins of Semliki Forest virus as exogenous acceptors, palmitic acid was incorporated into polypeptide in a cell-free system with microsomes of baby hamster kidney cells, chicken embryo fibroblasts, and rat liver cells. Out of the four viral proteins (E1, E2, E3, and C) only E1 becomes acylated enzymatically. The pr...
متن کاملEucaryotic replication origin binding proteins.
Initiation of eukaryotic DNA replication is a tightly controlled process. Replication initiates at multiple specific sites (replication origins) that have been licensed for replication, following the cell cycle-dependent, multi-step assembly of specific factors. Thus, replication origins occur in two chromatin states: a replication-competent pre-replicative (pre-RC) state, when a number of repl...
متن کاملAcylation of monocyte and glomerular mesangial cell proteins. Myristyl acylation of the interleukin 1 precursors.
Acylation of cellular proteins with the fatty acids myristate or palmitate represents an important mechanism for the co- or posttranslational modification of proteins. Lipid A, the biologically active component of bacterial endotoxin, exerts a number of biochemical effects on responsive cell types. Evidence is presented that lipid A stimulates the synthesis and subsequent myristyl acylation of ...
متن کاملFatty acid transport and fatty acid-binding proteins.
Les protkines de liaison ou de transfert des acides gras sont prCsentes dans les fluides intraet extra-cellulaires de la plupart des organismes. Elles jouent un r61e dans le transport ou le ciblage des acides gras, mais peuvent kgalement agir en interaction avec different processus par la modulation de la concentration de la liaison libre. Quelques protkines de liaison des acides gras sont asse...
