The trajectories of molecular dynamics simulation of phosphorylated S258 (CYP17A1), T162 and Y361 (CYP19A1) were analyzed to understand a possible mechanism of influence of post-translational modification (PTM) on the structure and functions of human sterol-hydroxylases CYP17A1 and CYP19A1. It was found that PTM has no dramatic influence on the structures of the enzymes but stabilizes them. According to our data, the phosphorylation of S258, T162 and Y361 influences the interface of interaction between human sterol-hydroxylases and the corresponding electron donors by decreasing the mobility of amino acids that take part in forming molecular complexes of the enzymes and the corresponding redox-partners. The phosphorylation of T162 (CYP19A1) decreases the mobility of amino acids forming access channel. The obtained results can shed light on the mechanism of fast regulation of human CYP17A1 and CYP19A1 activity by PTM.Π‘ ΡΠ΅Π»ΡΡ ΠΈΠ·ΡΡΠ΅Π½ΠΈΡ Π²Π»ΠΈΡΠ½ΠΈΡ ΠΏΠΎΡΡ-ΡΡΠ°Π½ΡΠ»ΡΡΠΈΠΎΠ½Π½ΡΡ

The analysis of the trajectories of molecular dynamics simulation and spatial structures of homologous models of fusion protein with various linkers was performed to understand the effect of the additional DNA-binding domain of the E. coli SSB protein attached to the truncated and native bovine DNA exotransferase on its stability and activity. It is found that the C-terminus of the enzyme is the preferred end for attachment of the E. coli protein, while the stability of the truncated fusion enzyme is higher than the native one. According to molecular dynamics data, introducing linkers between two proteins for the native (GGGGSGGGSGGGGS, GGGSGGGS, and TCT) and truncated (GGSGGGSGG, GGGGGG, GTGSGT, and 5xGGGGS) forms of the enzyme not only improves its stability, but also increases the mutual mobility of DNA-affinity domains.Π‘ ΡΠ΅Π»ΡΡ ΠΈΠ·ΡΡΠ΅Π½ΠΈΡ Π²Π»ΠΈΡΠ½ΠΈΡ Π΄ΠΎΠΏΠΎΠ»Π½ΠΈΡΠ΅Π»ΡΠ½ΠΎΠ³ΠΎ ΠΠΠ-ΡΠ²ΡΠ·ΡΠ²Π°ΡΡΠ΅Π³ΠΎ Π΄ΠΎΠΌΠ΅Π½Π° SSB-Π±Π΅Π»ΠΊΠ° E. coli, ΠΏΡΠΈΡΠΎΠ΅Π΄ΠΈΠ½Π΅Π½Π½ΠΎΠ³ΠΎ ΠΊ ΡΡΠ°Π½ΠΊΠΈΡΠΎΠ²Π°Π½Π½ΠΎΠΉ ΠΈ Π½Π°ΡΠΈΠ²Π½ΠΎΠΉ ΠΠΠ-ΡΠΊΠ·ΠΎΡΡΠ°Π½ΡΡΠ΅ΡΠ°Π·Π΅ Π±ΡΠΊΠ°, Π½Π° ΠΠΠ-Π°ΡΡΠΈΠ½Π½ΠΎΡΡΡ ΠΈ ΡΡΠ°Π±ΠΈΠ»ΡΠ½ΠΎΡΡΡ ΡΠ΅ΡΠΌΠ΅Π½ΡΠ°, ΠΏΡΠΎΠ²Π΅Π΄Π΅Π½ Π°Π½Π°Π»ΠΈΠ· ΡΡΠ°Π΅ΠΊΡΠΎΡΠΈΠΉ ΠΌΠΎΠ»Π΅ΠΊΡΠ»ΡΡΠ½ΠΎΠΉ Π΄ΠΈΠ½Π°ΠΌΠΈΠΊΠΈ ΠΈ ΠΏΡΠΎΡΡΡΠ°Π½ΡΡΠ²Π΅Π½Π½ΡΡ

In silico analysis of βprotein-ligandβ complexes of human CYP7 enzymes with modified borondipyrrome-tene (BODIPY) and steroids, containing photo-activated crosslinking groups, wasperformed in order to identify structural peculiarities of their interaction. It was found that BODIPY molecules and DHEA derivative with diazirine group are able to bind tightly with human steroid-hydroxylases. Binding affinity is comparable with corresponding values for essential ligands of the enzymes. Binding mode of the modified steroid corresponds to the binding mode of essential CYP7 ligands, so formation of hydroxylated products is possible. It was found that presence of both diazirine and NBD groups in a molecule significantly increases affinity of the compound in case of CYP7A1 and, especially, CYP7B1. Amino acid residues, located in a close proximity with photo-activated groups were detected, that can form covalent adducts with them. The obtained results can shed light on the mechanism of interaction of the compounds with recombinant human CYP7 enzymes in vitro. The results can also be used for the identification of modified amino acids of the proteins that are formed under photoactivation of the compounds in vitro.Π‘ ΡΠ΅Π»ΡΡ Π²ΡΡΠ²Π»Π΅Π½ΠΈΡ ΡΡΡΡΠΊΡΡΡΠ½ΡΡ
