Isolation and characterization of mutants from Schyzosaccharomyces pombe defective in glycerol catabolism. 1986

C Gancedo, and A Llobell, and J C Ribas, and F Luchi

Mutants unable to grow on glycerol were isolated from the fission yeast Schyzosaccharomyces pombe. Two types of mutants were obtained: one type was able to grow on dihydroxyacetone while the other one did not grow on this compound. The first type of mutants was defective in glycerol dehydrogenase while the second one was affected both in the glycerol dehydrogenase and in dihydroxyacetone kinase. It was found that the second type was defective in the derepression of several enzymes. The mutations were nuclear and monogenic and defined two complementation groups. Spontaneous revertants, able to grow on glycerol, were obtained from the first type of mutants. They have regained the glycerol dehydrogenase activity. The results presented provide genetic evidence for a pathway of glycerol catabolism in Sch. pombe involving dehydrogenation of glycerol as the first step followed by phosphorylation of the dihydroxyacetone formed.

D008540	Meiosis	A type of CELL NUCLEUS division, occurring during maturation of the GERM CELLS. Two successive cell nucleus divisions following a single chromosome duplication (S PHASE) result in daughter cells with half the number of CHROMOSOMES as the parent cells.

D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D010770	Phosphotransferases	A rather large group of enzymes comprising not only those transferring phosphate but also diphosphate, nucleotidyl residues, and others. These have also been subdivided according to the acceptor group. (From Enzyme Nomenclature, 1992) EC 2.7.	Kinases,Phosphotransferase,Phosphotransferases, ATP,Transphosphorylase,Transphosphorylases,Kinase,ATP Phosphotransferases
D003576	Electron Transport Complex IV	A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper atoms; and 13 different protein subunits. It is the terminal oxidase complex of the RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The redox reaction is simultaneously coupled to the transport of PROTONS across the inner mitochondrial membrane.
