1 CYP2C11 is the most abundant among the P450s present in untreated rat liver (approximately 50% of total P450) and is known for metabolizing testosterone mainly in positions 2 alpha and 16 alpha. Testosterone cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
2 Three mutations were identified in Gunn CYP2C11 form: Val4 --> Ala in the transmembrane region, Asn116 --> Ser in the substrate recognition site SRS-1, and Phe187 --> Leu in the (E --> F) interhelical region when compared to the spatial structure of CYP101. Alanine cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
3 Three mutations were identified in Gunn CYP2C11 form: Val4 --> Ala in the transmembrane region, Asn116 --> Ser in the substrate recognition site SRS-1, and Phe187 --> Leu in the (E --> F) interhelical region when compared to the spatial structure of CYP101. Serine cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
4 Three mutations were identified in Gunn CYP2C11 form: Val4 --> Ala in the transmembrane region, Asn116 --> Ser in the substrate recognition site SRS-1, and Phe187 --> Leu in the (E --> F) interhelical region when compared to the spatial structure of CYP101. Strontium cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
5 Three mutations were identified in Gunn CYP2C11 form: Val4 --> Ala in the transmembrane region, Asn116 --> Ser in the substrate recognition site SRS-1, and Phe187 --> Leu in the (E --> F) interhelical region when compared to the spatial structure of CYP101. Leucine cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
6 Testosterone-hydroxylating activities from CYP2C11 Gunn expressed in insect cells were decreased by 40% when compared to CYP2C11 Wistar, reflecting with a lesser extent the decrease we have previously reported in liver microsomes. Testosterone cytochrome P450, subfamily 2, polypeptide 11 Rattus norvegicus
