Human tryptophanyl-tRNA SYNTHETASE (Trp-RS, EC 6.1.1.2) can be separated from its mouse counterpart by Cellogel electrophoresis. Analysis of the presence or absence of human Trp-RS and other human enzyme markers in eleven independently dervied cell lines of human-mouse somatic cell hybrids revealed that the expression of Trp-RS is correlated with the expression of human nucleoside phosphorylase (NP, EC 2.4.2.1). The syntenic relationship between Trp-RS and NP permits the assignment of the structural gene for Trp-RS to human chromosome 14. Karyotype and isozyme analysis of these hybrid clones rules out other linkage assignments.
人色氨酰 - tRNA合成酶（Trp - RS，EC 6.1.1.2）可通过Cellogel电泳与小鼠对应物分离。对11个人 - 鼠体细胞杂交的独立衍生细胞系中人Trp - RS和其他人酶标志物的存在与否进行分析，结果表明Trp - RS的表达与人类核苷磷酸化酶（NP，EC 2.4.2.1）的表达相关。Trp - RS和NP之间的同线关系使得可以将Trp - RS的结构基因定位到人类14号染色体上。这些杂交克隆的核型和同工酶分析排除了其他连锁定位。
