CATA — Aspergillus nidulans FGSC A4

Summary

ANIA_08637 (symbol CATA, preferred name AnCATA) on chromosome 3 of Aspergillus nidulans FGSC A4 encodes a clade 2 catalase with haem-binding and metal-binding properties, classified as EC 1.11.1.6. This gene is associated with detoxification of hydrogen peroxide, the cellular response to oxidative stress, heat, and iron ion starvation, as well as osmolarity sensing and signal transduction. It has been linked to asexual and sexual reproduction, including conidia formation, sporulation, spore formation, and hyphal growth, and hypersensitivity. The product localises to the ascospore wall, peroxisomal lumen, cytosol, and extracellular. Studies of related genes in other species connect the family to germination rate and oxidative stress response.
