tailieunhanh - Prediction of glycation sites: New insights from protein structural analysis
Glycation of proteins is a nonenzymatic process in which proteins react with reducing sugar molecules. This process takes place at ε-amino (ε-NH+) groups of lysine or hydroxylysine residues as well as α-amino groups of N-terminal residues. In the present study glycation of ε-NH+ groups of lysines was computationally analyzed for 26 proteins based on their 3D structures. | Turkish Journal of Biology Turk J Biol (2016) 40: 12-25 © TÜBİTAK doi: Research Article Prediction of glycation sites: new insights from protein structural analysis 1, 2, 3 3 Homero SÁENZ-SUÁREZ *, Raúl A.

In the present study glycation of ε-NH+ groups of lysines was computationally analyzed for 26 proteins based on their 3D structures. We determined the spatial relationship with acidic or basic residues and correlated them with the glycation prediction algorithm Netglycate software, which .
