CATA — Neurospora crassa

Summary

NCU08791 (CATA, cat-1) on Neurospora crassa chromosome 3 encodes a clade 2 catalase with catalase activity (EC 1.11.1.6), heme binding, and metal binding. The gene is associated with responses to oxidative stress, hydrogen peroxide, superoxide, heat, and iron ion starvation, as well as heme and protein oxidation, the MAPK cascade, circadian rhythm, osmolarity sensing, asexual sporulation, spore germination, digestion, and carotene anabolism. The encoded protein localises to the ascospore wall, peroxisomal lumen, cytosol, and extracellular space. The gene is linked to germination rate. Studies of related genes in other species connect the family to oxidative stress response and to pathogens such as Verticillium dahliae and Fusarium oxysporum.
