General Information

Description Catalase isozyme 2 (EC 1.11.1.6) - Gossypium hirsutum (Upland cotton), Encodes a peroxisomal catalase, highly expressed in bolts and leaves. mRNA expression patterns show circadian regulation with mRNA levels being high in the subjective early morning. Loss of function mutations have increased H2O2 levels and increased H2O2 sensitivity. Mutants accumulate more toxic ions yet show decreased sensitivity to Li . This decreased sensitivity is most likely due to an insensitivity to ethylene. Note that in Queval et al. (2007) Plant Journal, 52(4):640, SALK_057998 is named as cat2-1, SALK_076998 is named as cat2-2 | in Bueso et al. (2007) Plant Journal, 52(6):1052, SALK_076998 is named as cat2-1. TAIR has adopted the nomenclature consistent with that in Bueso et al. (2007) after consultation with the authors: SALK_076998 (cat2-1), SALK_057998 (cat2-2). | catalase 2 (CAT2) | FUNCTIONS IN: protein binding, catalase activity, cobalt ion binding | INVOLVED IN: in 10 processes | LOCATED IN: mitochondrion, cytosolic ribosome, stromule, peroxisome | EXPRESSED IN: 24 plant structures | EXPRESSED DURING: 16 growth stages | CONTAINS InterPro DOMAIN/s: Catalase-like domain, haem-dependent , Catalase related subgroup , Catalase , Catalase, N-terminal , Catalase-related immune responsive | BEST Arabidopsis thaliana protein match is: catalase 1
