In humans, genetic defects of CathA cause galactosialidosis, a metabolic disease characterized by combined deficiency of CathA, GAL, and Neu1 and a lysosomal storage of sialylated glycoconjugates.

在人类，CathA的遗传缺失可引起半乳糖唾液酸沉积症，一种以CathA、 GAL、 Neu1不足和唾液酸化糖结合物在溶酶体的沉为特征的代谢疾病。

The GPA1 gene was obtained via PCR amplification and was cloned in the two-hybrid DNA binding domain vector pGBKT7 The combinant plasmid was designated as pGBKT7-Ga.β-galactosidase assay indicatedthat Got did not have the property of self-activation. After pGBKT7-Ga was transformed to yeast pJ69-4A, we transformed Arabidopsis vegetative tissue two-hybrid cDNA library plasmids to yeast pJ69-4A containing pGBKT7-Ga.

通过PCR扩增得到GPA1基因并将其克隆到双杂交DNA结合域载体pGBKT7中，得到的重组质粒命名为pGBKT7-Gα，β—半乳糖苷酶活性鉴定表明Gα不具有自激活特性，将其转化到酵母菌pJ69-4A中，再以此为受体菌转化拟南芥绿色营养组织cDNA文库质粒。

IPTG was used to induce expression in BL21, and some enzymic indexes of expressed proteins were detected.

用异丙基-β-D-硫代半乳糖苷诱导表达菌并测定表达蛋白的酶学参数。

A polygalacturonase inhibiting protein gene named FaPGIP was cloned from strawberry (Fragaria × ananassa) leaves through PCR.

以草莓（Fragaria × ananassa）叶片为试材，采用PCR技术，克隆到1条多聚半乳糖醛酸酶抑制蛋白基因，命名为FaPGIP。

Although the deelopment of relatiely non-toxic immunosuppressie or tolerance-inducing regimens will be required to justify clinical trials using pig organs, recent adances in our understanding of the biology of xenograft rejection and zoonotic infections, and the generation of alpha1,3-galactosyltransferase-deficient pigs hae moed this approach closer to clinical application.

尽管用猪的器官去验证临床试验需要相对无毒的免疫抑制剂或致耐的方法，但随着近来我们对异种移植排斥生物学及动物传染病感染的深入理解，以及α1，3 半乳糖转移酶缺陷猪的产生，异种移植更接近临床应用。

The effect of activities of polygalacturoase on pathogenicity in Phytophthora sojae was investigated.

就大豆疫霉根腐病菌多聚半乳糖醛酸酶（Polygalacturonase，PG）活性对其致病力的影响进行了研究。

Objective To observe the replicative senescence-related beta-galactosidase activity in cultured human retinal pigment epithelium cells.
