GGP

GDP-L-半乳糖磷酸化酶(GGP)

抗坏血酸代谢途径中的 GGP 基因编码 GDP - L - 半乳糖磷酸化酶。它在催化 GDP-L-半乳糖转化为 L-半乳糖-1-磷酸盐方面起着至关重要的作用，这是抗坏血酸生物合成的重要步骤。该反应为随后合成抗坏血酸提供了必要的前体。通过调节 GGP 的活性，细胞可以控制前体的供应，从而影响抗坏血酸的最终合成和含量，在维持抗坏血酸代谢的平衡中起关键作用。

GDP-L-galactose phosphorylase(GGP)

The GGP gene in the ascorbic acid metabolic pathway encodes GDP - L - galactose phosphorylase. It plays a crucial role in catalyzing the conversion of GDP - L - galactose to L - galactose - 1 - phosphate, which is an important step in ascorbic acid biosynthesis. This reaction provides the necessary precursor for the subsequent synthesis of ascorbic acid. By regulating the activity of GGP, the cell can control the supply of precursors and thus affect the final synthesis and content of ascorbic acid, playing a key role in maintaining the balance of ascorbic acid metabolism.
