Trans-AT 聚酮合成酶（PKSs）是一类能够合成大量结构特殊、活性多样的聚酮分子的酶。这些酶中同时存在多种特殊模块或结构域，如β-分支模块、分支结构域和BV氧化结构域等，可在装配线上直接对延伸的聚酮骨架进行修饰，增加产物的结构多样性。然而，在trans-AT PKS的非经典催化过程中，单一模块或功能域的迭代使用过程尤为特殊。
Trans Effects in Nitric Oxide Binding to Myoglobin Cavity Mutant H93G
biology and medicine, basic studies nitric oxide biochemistry heme histidine imidazoles ligands mutants myoglobin proteins
2016/5/23
When nitric oxide (NO) binds to heme proteins, it exerts a repulsive trans effect on the proximal ligand, resulting in weakening or rupture of the proximal ligand-iron bond. The general question of wh...

Genetic loci associated with circulating phospholipid trans fatty acids: a meta-analysis of genome-wide association studies from the CHARGE Consortium
arachidonic acid genome-wide association meta-analysis phospholipid trans fatty acids
2018/12/20
Background: Circulating trans fatty acids (TFAs), which cannot be synthesized by humans, are linked to adverse health outcomes. Although TFAs are obtained from diet, little is known about subsequent i...
Differential Action of trans-10, cis-12 Conjugated Linoleic Acid on Adipocyte Differentiation of Ovine and 3T3-L1 Preadipocytes
trans-10 cis-12 CLA Adipocyte Sheep
2016/5/3
Trans-10, cis-12 conjugated linoleic acid (CLA) has been reported to inhibit the adipocyte differentiation of preadipocytes in non-ruminant animals (mice, rat, and human). However, the effects of tran...
The Genetic Diversity of Trans-caucasian Native Sheep Breeds
Domestication Sheep Micro-satellites
2016/4/21
The genetic variation in 10 indigenous Caucasian sheep breeds was studied with 14 micro-satellite loci in order to determine the genetic diversity among and between the breeds. Five breeds from Asia, ...
