Sentence examples for by coordination to a from inspiring English sources

The symmetry of an anion is lowered by coordination to a cation.

Proton abstraction generates an enolate intermediate that is stabilized by coordination to a conserved magnesium ion.

For the proton abstraction to be kinetically competent, the intermediate is stabilized by coordination to a required Mg2+ ion.

A quadruplex comprises two or more stacked G-tetrads: planar arragements of four Hoogsteen hydrogen bonded guanine bases, which are further stabilized by coordination to a central monovalent cation.

It is well established [ 5] that one role of tetrabutylammonium bromide and related species in cyclic carbonate synthesis is to open the epoxide ring to form a bromo-alkoxide (which can be stabilized by coordination to a metal catalyst such as 1), which then reacts with carbon dioxide and cyclizes to give the cyclic carbonate with regeneration of the tetrabutylammonium bromide catalyst (Scheme 2).

The enediolate intermediate is stabilized by coordination to an active site divalent metal cation (usually Mg2+).

We observed three well-separated protein peaks with different affinities to the column; peaks (a) and (b) with multiple and one NTA attached to the His6-tag by coordination to Co3+, respectively, have a lower affinity to the column, and peak (c) corresponds to unmodified His6-GFP.

The first step of the cycle involves protonation of the double bond of 5 by a proton donor (e.g., thiophenol 2 a), acidified by coordination to AuCl.

The bidentate coordination behaviour of a nitrite anion is used to template the formation of a pseudorotaxane assembly, by simultaneous coordination to a lanthanide cation incorporated within a macrocycle and a hydrogen-bond donor threading component.

The ATP ligand is further stabilized by coordination to several additional bound water molecules.

This orientation would allow facile attack of the bridging hydroxide at the lactone's carbonyl carbon, polarization of this carbonyl bond by coordination of oxygen to Zn1, and stabilization of the leaving group heteroatom by coordination to Zn2.
