Sequence Description Alias PCC hrr evm.model.tig00020610.135 (at5g50700 : 80.5) Encodes a hydroxysteroid dehydrogenase HSD1. Two copies of HSD1 (At5g50600 and At5g50700) exist in the Arabidopsis genome as a result of an exact 33-kb duplication on chromosome 5 encompassing seven genes. There are five homologs of HSD1 in Arabidopsis (HSD2-At3g47350, HSD3-At3g47360, HSD4-At5g50590, HSD4-At5g50690 and HSD6-At5g50770; HSD4 has two copies due to the same gene duplication event occurred to HSD1) (Plant Cell Physiology 50:1463). At5g50690 is also named as HSD7 (Plant Physiology 145:87). HSD1 is identified from the proteome of oil bodies from mature seeds. Transcription of HSD1 is specifically and highly induced in oil-accumulating tissues of mature seeds; transcript disappears during germination.; hydroxysteroid dehydrogenase 1 (HSD1); FUNCTIONS IN: oxidoreductase activity, binding, catalytic activity; INVOLVED IN: oxidation reduction, metabolic process; LOCATED IN: endomembrane system; EXPRESSED IN: seed; CONTAINS InterPro DOMAIN/s: Short-chain dehydrogenase/reductase, conserved site (InterPro:IPR020904), NAD(P)-binding domain (InterPro:IPR016040), Glucose/ribitol dehydrogenase (InterPro:IPR002347), Short-chain dehydrogenase/reductase SDR (InterPro:IPR002198); BEST Arabidopsis thaliana protein match is: hydroxysteroid dehydrogenase 1 (TAIR:AT5G50600.1); Has 30201 Blast hits to 17322 proteins in 780 species: Archae - 12; Bacteria - 1396; Metazoa - 17338; Fungi - 3422; Plants - 5037; Viruses - 0; Other Eukaryotes - 2996 (source: NCBI BLink). & (reliability: 161.0) & (original description: no original description) 0.698601591302653 15 evm.model.tig00000946.2 no hits & (original description: no original description) 0.6702943867856116 27 evm.model.tig00020611.4 no hits & (original description: no original description) 0.6149521324332504 52 evm.model.tig00000158.119 no hits & (original description: no original description) 0.5953356731221255 7 evm.model.tig00020531.8 no hits & (original description: no original description) 0.5589234767404959 53 evm.model.tig00001030.38 no hits & (original description: no original description) 0.5552387167979509 50 evm.model.tig00000734.2 no hits & (original description: no original description) 0.5365793686633546 98 evm.model.tig00021221.4 no hits & (original description: no original description) 0.5294905732793498 23 evm.model.tig00000430.29 no hits & (original description: no original description) 0.5292101039983622 83 evm.model.tig00020912.45 no hits & (original description: no original description) 0.5213672720304685 72 evm.model.tig00020563.57 no hits & (original description: no original description) 0.5194132360747211 92 evm.model.tig00020902.92 no hits & (original description: no original description) 0.5090576722983797 92 evm.model.tig00021070.30 no hits & (original description: no original description) 0.5085599982249401 57
