ADSL基因介绍 was created by 凤凰

ADSL基因产物:腺苷酸琥珀酸裂解酶(Adenylosuccinate lyase,ADSL)。

蛋白功能:是一种参与嘌呤核苷酸代谢2条途径的酶,它可以催化琥珀酰基的裂解产生富马酸盐:琥珀酰氨基咪唑甲酰胺核糖核苷酸(SAICAR)沿从头途径转化为氨基咪唑甲酰酰胺核糖核苷(AICAR),以及腺苷酸(AMP)在嘌呤核苷酸循环中由腺苷酸琥珀酸酯(S-AMP)转化为腺嘌呤核苷酸(IMP)形成腺苷酸盐(AMP)。

相关疾病:腺苷酸琥珀酸缺乏症(AR)(部分可表现为 婴儿癫痫性痉挛综合征 Lennox-Gastaut 综合征 婴儿癫痫伴游走性局灶性发作 )[1]。

用药提醒目前尚无该病的酶替代疗法,有报道称D-核糖和生酮饮食对部分患者有效[1]。
