Through covalent interaction with target protein, small molecular SUMO affects target proteins' stability, cellular localization and interactions with other proteins to regulate a series of important processes including transcriptional regulation.

小蛋白分子SUMO通过与靶蛋白的共价连接，影响了靶蛋白的稳定性、细胞定位、蛋白质间的相互作用等，参与了转录调控等重要生理过程。

The results show that intramolecular coordination ability bears a parallel relationship with stabilization energy, bond parameter and charge transfer. For these coordination compounds intramolecular interaction is mainly a σ-bonding and the coordination force is essentially covalent interaction.

结果表明，分予闻配位强弱与稳定化能、键参量、电荷转移成平行关系，分子间作用键主要是σ配键，揭示了配位力的本质是授受电子的共价作用。

The moiety can provide covalent interaction with sugars.

其含有硼酸部分，可以与醣类分子以共价键键结。

The results showed that the relative order of complexing action mainly depends on the order of covalent interaction, rather than electrostatic interaction.

结果表明，决定络合作用力相对顺序的主要因素是给受电子共价作用。

Tuning the intermolecular interaction of such kind of tetrapyrrole derivatives can be easily reached by introducing functional groups ( actually additional non-covalent interactions) onto the peripheral positions of porphyrin ring.

所以，调控卟啉类化合物及其衍生物的分子间弱作用可以很容易地通过在卟啉环或其衍生物的外围引入不同的官能团（实际上是通过引入官能团来引入非共价弱作用）来实现。

The non-covalent interaction of 7-hydroxy flavone and its phosphate with DNA was studied using ethidium bromide ( EB) as a probe.

以溴化乙锭（EB）为荧光探针，研究了7-羟基黄酮及磷酰化7-羟基黄酮与DNA的弱相互作用。
