small subunit

Small subunits were dissociated from the large subunit core ( L8) at pH 6.0 while the latter was still bound to the matrix.

在pH6.0时，仅小亚基从大亚基核（L8）解离，当pH为中性偏碱时，大亚基核也解离。

Small GTPases are monomeric guanine nucleotide binding proteins coupled to the α-subunit of heterotrimeric G proteins. All small GTPases belong to Ras superfamily.

小G蛋白是和异三聚体G蛋白α亚基偶联的单体鸟苷酸结合蛋白，所有的小G蛋白从属于Ras超家族。

Caspase-3 proenzyme is composed of one large-subunit and one small-subunit and only after being cut and activated can Caspase-3 perform its function.

该酶原由一个大亚基和一个小亚基组成，只有被切开并激活后Caspase-3才能够行使其功能。
