Probable tauropine-mediated interaction between marine redalgae and marine bacteria

为了阐明牛磺酸在巨形目(红藻门)中的有限分布的生理作用，我们假设并证明了牛磺酸介导的海洋藻类与海洋细菌之间的相互作用。从反常毛藻中分离纯化了牛油碱脱氢酶(AHP-TaDH1和AHP-TaDH2)，并测定了其催化性质、N-末端和部分氨基酸序列。然而，利用部分氨基酸序列信息克隆牛磺酸脱氢酶基因是不完整的。

To elucidate the physiological role of tauropine (rhodoic acid) which shows limited distribution among Gigartinales (Rhodophyta), the tauropin-mediated interaction between marine algae and marine bacteria was assumed and demonstrated. Tauropine dehydrogenases （ Ahp-TaDH1 and Ahp-TaDH2 ） were highly purified from Ahnfeltiopsis paradoxa.The catalytic properties and N-terminus and the partial amino acid sequences were determined. However, cloning of the tauropine dehydrogenase cDNA using partial amino acid sequence information was incomplete.
