glutathione synthetase


Also found in: Acronyms, Wikipedia.

glu·ta·thi·one syn·the·tase

[MIM*601002]
an enzyme that catalyzes the formation of glutathione, ADP, and orthophosphate from γ-glutamylcysteine, ATP, and glycine; a deficiency will lead to metabolic acidosis and progressive brain dysfunction.

glutathione synthetase

/glu·ta·thi·one syn·the·tase/ (sin´thĕ-tās) a ligase catalyzing the formation of glutathione; deficient activity causes decreased levels of glutathione and increased levels of 5-oxoproline and cysteine. If confined to erythrocytes, the deficiency results in well-compensated hemolytic anemia; if generalized, metabolic acidosis and neurologic dysfunction may also occur.

glutathione synthetase

One of the enzymes concerned in the synthesis of GLUTATHIONE from glutamate.

The failure of gene fragment amplification in cyanobacterial stains analogue to glutathione synthetase (gshB), except Synechocystis AHZ- HB-MK" and Synechocystis AHZ-HB-P2A" strains, may have one explanation that the primers designed for glutathione synthetase gene probably was not form conserved region of this gene, in other cyanobacteria (Jeff Elhai, personal communication), so Synechocystis strains gave amplification, while other cyanobacterial strains did not give amplification for it.
Two genes glutathione synthetase and glutaredoxin 3 are involved in glutathione synthesis and reduction of oxidized form of glutathione (GSSG in to GSH) to reduced form for its further use to overcome oxidative stress by binding with heavy metals [3].
Strain Synechocystis AHZ- HB-MK" is not only different from Synechocystis AHZ-HB- P2A" on the bases of glutathione synthetase gene homology which is greater in case of Synechocystis AHZ-HB-MK", but also from the other aspects.
