2.4.1.255 | protein O-GlcNAc transferase |
cocrystallization of identified substrate peptides with OGT, derived from retinoblastoma-like protein 2 (RBL2411-422, KENPAVTPVSTA), proto-oncogene tyrosine protein kinase receptor Ret (Ret660-672, AQAFPVSYSSSGA), keratin-7 (KER77-19, SPVFTSRSAAFSC) and lamin B1 (LAMIN179-191, KLSPSPSSRVTVS). The peptide is tethered into a common binding mode by a combination of van der Waals interactions and hydrogen bonds that restrict torsional freedom in the -3 to +2 subsites only |

2.4.1.255 | protein O-GlcNAc transferase |
hybrid quantum mechanics/molecular mechanics analysis of reaction paths using alpha-phosphate and Asp554 as the catalytic bases. The mechanism with alpha-phosphate acting as the base is favorable. The reaction has a rate-limiting free energy barrier of 23.5 kcal/mol, whereas reactions utilizing Asp554 and water-assisted alpha-phosphate have barriers of 41.7 and 40.9 kcal/mol, respectively |

in complex with inhibitor goblin1, to 3.15 A resolution. UDP adopts the same conformation as observed in the OGT Michaelis complex and the peptide occupies the -4 to +2 subsites with a similar backbone conformation. The three-carbon linker connects the two components without introducing any strain, allowing both the UDP moiety and the peptide part of the inhibitor to adopt the optimal position in the binding site, mimicking the natural substrates |
