Genetics of yeast glucokinase.
Mutants of Saccharomyces cerevisiae lacking glucokinase (EC 2.7.1.2) have no discernible phenotypic difference from the wild-type strain; in a hexokinaseless background, however, they are unable to grow on any sugar except galactose. Reversion studies with glucokinase mutants indicate that the yeast S. cerevisiae has no other enzyme for phosphorylating glucose except the two hexokinases, P1 and...
متن کاملGlucokinase gene structure. Functional implications of molecular genetic studies.
Glucokinase is expressed in both the liver and the pancreatic beta-cell and plays a key role in the metabolism of glucose by both tissues. Expression of this enzyme is differentially regulated; hepatic glucokinase is stimulated by insulin and repressed by cAMP, whereas beta-cell glucokinase activity is increased by glucose. Recently, the glucokinase gene has been characterized and was found to ...
متن کاملFunctional Studies of Vesicular Transport in Yeast
Barmark, G. 2005. Functional studies of vesicular transport in yeast. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-6909-0 A basic feature of eukaryotic cells is their compartmental organisation. To maintain this cellular order, a strictly regulated intracellular transport is essential. The compartments are defined by their lipid membranes and the transport between different compartments i...
متن کاملCloning of genes that complement yeast hexokinase and glucokinase mutants.
Genes complementing the glucose-negative fructose-negative Saccharomyces cerevisiae triple mutant strain (hxkl hxk2 glk1), which lacks hexokinase PI, hexokinase PII, and glucokinase, were obtained from a pool of yeast DNA in the multicopy plasmid YEp13.
متن کاملFunctional Studies of Plasma Membrane Syntaxins in Yeast
Öyen, M. 2003. Functional studies of plasma membrane syntaxins in yeast. Doctor’s dissertation. ISSN 1401-6249, ISBN 91-576-6480-03 Syntaxins are required for fusion of membranes in eukaryotic cells and belong to a group of proteins known as t-SNAREs. This thesis primarily focuses on the role of the plasma membrane syntaxins Sso1p and Sso2p in the yeast Saccharomyces cerevisiae. The plasma memb...
