Ctt1 catalase activity potentiates antifungal azoles in the emerging opportunistic pathogen Saccharomyces cerevisiae.
Title: Ctt1 catalase activity potentiates antifungal azoles in the emerging opportunistic pathogen Saccharomyces cerevisiae.
In cells that underwent multiple rounds of H2O2 treatments, we identified a genetic alteration that resulted in improved H2O2 tolerance by amplification of the CTT1 gene that encodes cytosolic catalase T. Lastly, we showed that cells grown in the absence of oxygen have reduced levels of recombination.
Title: Genome-wide analysis of genomic alterations induced by oxidative DNA damage in yeast.
MET18 deficiency diminished the replicative capacity of yeast cells as evidenced by the shortened replicative lifespan, which can be restored by CTT1 overexpression, but not by CTA1, in the MET18-deficient cells.
Title: MET18 Deficiency Increases the Sensitivity of Yeast to Oxidative Stress and Shortens Replicative Lifespan by Inhibiting Catalase Activity.
the KSP1 deficiency also leads to a shortened replicative lifespan, which could be restored by the increased expression of CTT1. On the other hand, KSP1-overexpressed (KSP1OX) yeast cells exhibited increased resistance towards MMS, an effect that was, at least in part, CTT1 independent.
Title: CTT1 overexpression increases the replicative lifespan of MMS-sensitive Saccharomyces cerevisiae deficient in KSP1.
CTT1 overexpression increases life span of calorie-restricted Saccharomyces cerevisiae deficient in Sod1.
Title: CTT1 overexpression increases life span of calorie-restricted Saccharomyces cerevisiae deficient in Sod1.
Data suggest that induction of cytosolic Ctt1 activity is vital in protecting yeast against exogenous H2O2 but this activity is inhibited by H2O2 when cells are challenged in nutrient-free media.
Title: Catalase activity is stimulated by H(2)O(2) in rich culture medium and is required for H(2)O(2) resistance and adaptation in yeast.
This report is first of its kind regarding the novel role of catalase in peroxynitrite detoxification in Deltayhb1 and Deltasfa1 strains of S. cerevisiae.
Title: A novel role of catalase in detoxification of peroxynitrite in S. cerevisiae.
reduction in hydrogen peroxide is the result of a Sir2p and actin cytoskeleton-dependent segregation of the cytosolic catalase Ctt1p such that the daughter cell receives a higher load of undamaged and active Ctt1p than the progenitor cell
Title: Sir2p-dependent protein segregation gives rise to a superior reactive oxygen species management in the progeny of Saccharomyces cerevisiae.
