GDP-α-D-mannose disodium(GDP-α-D-甘露糖)

GDP-α-D-mannose disodium 是甘露糖基转移酶的供体底物，是 GDP-β-L-fucose 的前体。GDP-α-D-mannose disodium 对 GTP 具有竞争性抑制作用 (K_i 为 14.7 μM)，对 mannose-1-P 具有非竞争性抑制作用 (K_i 为 115 μM)。

Background:

GDP-α-D-mannose disodium is the donor substrate for mannosyltransferases and the precursor of GDP-β-L-fucose. GDP-α-D-mannose disodium gives a competitive inhibition with respect to GTP (Ki 14.7 μM) and an uncompetitive inhibition with respect to mannose-1-P (Ki 115 μM)[1].

GDP-α-D-mannose is the alpha-anomer of GDP-D-mannose.
