Sequence Description Alias PCC hrr Kfl00698_0020 (at3g01910 : 230.0) Encodes a homodimeric Mo-enzyme with molybdopterin as organic component of the molybdenum cofactor. It lacks the heme domain that other eukaryotic Mo-enzymes possess and has no redox-active centers other than the molybdenum. SO protein has been found in all parts of the plant. The plant SO combines its enzymatic sulfite oxidation with a subsequent nonenzymatic step using its reaction product H2O2 as intermediate for oxidizing another molecule of sulfite.; sulfite oxidase (SOX); FUNCTIONS IN: sulfite oxidase activity; INVOLVED IN: sulfur metabolic process, response to sulfur dioxide, chlorophyll metabolic process; LOCATED IN: mitochondrion, peroxisome; EXPRESSED IN: 29 plant structures; EXPRESSED DURING: 15 growth stages; CONTAINS InterPro DOMAIN/s: Immunoglobulin E-set (InterPro:IPR014756), Eukaryotic molybdopterin oxidoreductase (InterPro:IPR008335), Moybdenum cofactor oxidoreductase, dimerisation (InterPro:IPR005066), Oxidoreductase, molybdopterin-binding domain (InterPro:IPR000572); BEST Arabidopsis thaliana protein match is: nitrate reductase 1 (TAIR:AT1G77760.1); Has 3266 Blast hits to 3265 proteins in 737 species: Archae - 124; Bacteria - 1570; Metazoa - 141; Fungi - 268; Plants - 245; Viruses - 0; Other Eukaryotes - 918 (source: NCBI BLink). & (p27968|nia7_horvu : 200.0) Nitrate reductase [NAD(P)H] (EC 1.7.1.2) - Hordeum vulgare (Barley) & (reliability: 460.0) & (original description: no original description) kfl00698_0020_v1.1 0.6607755314009263 58 Kfl00801_0010 no hits & (original description: no original description) kfl00801_0010_v1.1 0.6463594582350554 36 Kfl01192_0010 no hits & (original description: no original description) kfl01192_0010_v1.1 0.6448509706847222 38
