摘要

在对秀丽隐杆线虫镉反应基因的鉴定中,分离出丙酮酸羧化酶的同源物作为表达序列标签。该秀丽隐杆线虫蛋白被命名为PYC-1,预计含有1175个氨基酸,分子质量为129284。氨基酸序列分析表明PYC-1将易位到线粒体中。PYC-1与其他丙酮酸羧化酶具有高度的氨基酸序列一致性。最高水平的同一性是在假定的转羧化,生物素羧化和生物素羧基载体结构域。

Characterization of a Cadmium-Inducible Isoform of Pyruvate Carboxylase from Caenorhabditis elegans
A homologue of pyruvate carboxylase was isolated as an expressed sequence tag during the identification of cadmium-responsive genes in Caenorhabditis elegans. The C. elegans protein, designated PYC-1, is predicted to contain 1,175 amino acids with a molecular mass of 129,284. Amino acid sequence analysis indicates that PYC-1 will be translocated into mitochondria. PYC-1 has high levels of amino acid sequence identity with other pyruvate carboxylases. The highest levels of identity are in the putative transcarboxylation, biotin carboxylation and biotin carboxyl carrier domains.
