Abstract (sommario):
CYP199A4 is a cytochrome P450 and can catalyze the hydroxylation of 4-propionylbenzoic acid (4-pIBA) to generate α-hydroxyketone with high stereoselectivity. The F182L mutant of CYP199A4 (F182L-CYP199A4) has been shown to support the cleavage of the C–C bond between the carbonyl and hydroxyl groups of α-hydroxyketone, whereas wild-type CYP199A4 cannot. To uncover how the Phe182 regulates substrate reactivity, we conducted classical molecular dynamics (MD) and quantum mechanics/molecular mechanics (QM/MM) MD simulations on these systems. The results predicted that the formation of α-hydroxyketo

Abstract (sommario):
Proper, tissue-specific regulation of CYP19, the gene encoding aromatase, the key enzyme of estrogen synthesis, is essential for reproductive processes. Here, we analyzed transcriptional regulation of the porcine CYP19 in female and male gonads and brain by 5’RACE and RT-PCR and comprehensively mapped the pig CYP19 locus by in silico analysis. Our data revealed that the complete locus, including three paralogous copies, CYP19A1, CYP19A2 and CYP19A3, spans approximately 330 kb of the porcine chromosome 1. The locus also harbors the first exon of the Gliomedin gene (GLDN) in reverse orientation.

A etiologia multifatorial e comprometimento poligênico nesta doença têm sido amplamente aceitos. A aromatase é uma molécula das mais estudadas e há evidências de aumento da expressão do seu gene no endométrio eutópico e ectópico na endometriose.
