Prediction of alternate structures of CYP102A1 The competitive modelling approach was designed considering that the CYP102A1 FMNd must form alternate electron transfer complexes with the FADd and the P450d to support catalytic cycles, but that a direct electron transfer from FADd to P450d is not possible. In the dimeric structure…

Introduction Escherichia coli is a common Gram-negative opportunistic pathogen that causes invasive host infections through virulence factors such as flagella, toxin secretion, and adhesins. According to the source of the infection, pathogenic E. coli can be classified as intestinal (diarrheagenic) and extraintestinal (ExPEC). Uropathogenic E. coli (UPEC) is the most…
