In this pathway, 4-alpha-methyl-5-alpha-cholest-7-en-3-beta-ol is enzymatically converted to 4-alpha-methyl-5-alpha-cholest-7-en-3-one via the enzyme 3-keto-steroid reductase [EC: 1.1.1.270] and the cofactor NADP(+). This enzyme is responsible for the reduction of the keto group on the C-3 of sterols.","experimental_water_solubility":"","experimental_logp_hydrophobicity":"","location":"Endoplasmic Reticulum Membrane","synthesis_reference":null,"chebi_id":"18378","hmdb_id":"HMDB11605","kegg_id":"C08825","pubchem_id":"160482","cs_id":"25994938","foodb_id":null,"wikipedia_link":null,"biocyc_id":"CPD-5847","iupac":"(1R,2S,5S,6S,7S,11R,15R)-2,6,15-trimethyl-14-[(2R)-6-methylheptan-2-yl]tetracyclo[8.7.0.0^{2,7}.0^{11,15}]heptadec-9-en-5-ol","traditional_iupac":"(1R,2S,5S,6S,7S,11R,15R)-2,6,15-trimethyl-14-[(2R)-6-methylheptan-2-yl]tetracyclo[8.7.0.0^{2,7}.0^{11,15}]heptadec-9-en-5-ol","logp":"7.477861857000003","pka":null,"alogps_solubility":"2.98e-05 g/l","alogps_logp":"7.34","alogps_logs":"-7.13","acceptor_count":"1","donor_count":"1","rotatable_bond_count":"5","polar_surface_area":"20.23","refractivity":"125.08809999999997","polarizability":"51.94485402734399","formal_charge":"0","physiological_charge":"0","pka_strongest_basic":"-1.0677290518229814","pka_strongest_acidic":"18.957638198850066","bioavailability":"1","number_of_rings":"4","rule_of_five":"0","ghose_filter":"0","veber_rule":"1","mddr_like_rule":"0","synonyms":["4-a-Methyl-5-a-cholest-7-en-3-b-ol","4-alpha-Methyl-5-alpha-cholest-7-en-3-beta-ol","4-Methylcholest-7-en-3-ol","4-Methylcholest-7-en-3-ol, (3beta,4alpha)-isomer","4alpha-Methyl-5alpha-cholest-7-en-3beta-ol","Lophenol","Methostenol"],"pathways":[],"growth_conditions":[],"references":[{"pubmed_id":21051339,"citation":"UniProt Consortium (2011). \"Ongoing and future developments at the Universal Protein Resource.\" Nucleic Acids Res 39:D214-D219."}],"proteins":[{"created_at":"2011-05-24T20:59:15.000Z","updated_at":"2011-07-22T17:54:20.000Z","name":"3-keto-steroid reductase","uniprot_id":"Q12452","uniprot_name":"ERG27_YEAST","enzyme":true,"transporter":false,"gene_name":"ERG27","num_residues":347,"molecular_weight":"39724.39844","theoretical_pi":"8.64","general_function":"Involved in binding","specific_function":"Responsible for the reduction of the keto group on the C-3 of sterols.
