spinqualitylabelsall models α-2,3-sialyltransferase complex with trisaccharide, acetate, MPD and ethylene glycol (PDB code 2x61) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function Sialyltransferase (SIT) is involved in maintaining or increasing cell surface sialysation which contributes to adhesive cellular interactions and thus to the growth and differentiation of hematopoietic progenitor cells[1]. Relevance Elevated SIT activity leads to overexpression of cell surface sialic acids and contributes to many disease developments such as cancer and inflammation[2]. Structural highlights The biological assembly of α-2,3-sialyltransferase is (2x61). The at the C-terminal of SIT[3]. . Water molecules shown as red spheres.
