	Oxyanion-catalyzed polymerization - Patent 4588795
		By conjugate acid is meant the acid formed by protonating the catalytic oxyanion; for example, the conjugate acid of acetate anion is acetic acid, and that of biacetate anion is acetic acid dimer.
		Oxyanion salts which are operable in the present invention contain cations that are inert under polymerizing conditions, yet render the catalyst available in the polymerizing medium; the medium can include one or more solubilizing agents, such as crown ethers.
		Oxyanion sources which are particularly useful in the present invention include salts of carboxylic and bicarboxylic acids, sulfinic acids, phosphinic and phosphoric acids, phenols and biphenols, nitrous and cyanic acids, trihydrocarbylsilanols, and higher oligomeric forms of these acids, having the aforesaid pKa.

		Oxyanion Binding Alters Conformation and Quaternary Structure of the C-terminal Domain of the Transcriptional Regulator ModE.
		The residues of ModE directly involved in oxyanion binding are marked with triangles, shaded to indicate the use of a side chain functional group and open where a main chain amide is used for binding.
		Only those sites at the dimer interface that bind 6 oxyanions are shown; the other sites are buried at the trimer interface behind subunit A in one case and subunit D in the other.

	X-ray snapshots of serine protease catalysis reveal a tetrahedral intermediate - Nature Structural & Molecular ...
		An oxyanion hole, consisting of the peptide amide of the active site serine and a neighbouring glycine, was identified, and hydrogen bonding in the oxyanion hole was suggested to stabilize the two proposed tetrahedral intermediates on the catalytic pathway.
		The refined distances between the 'oxyanion' of the tetrahedral intermediate and the amide nitrogens of Gly 193 and Ser 195 were 2.9 Å and 2.6 Å, respectively (Fig.
		Furthermore, the oxyanion is positioned 3.0 Å from the carbonyl oxygen of Cys 191 (Fig.

		To name such an acid, first write a form of the root of the name of the oxyanion.
		If the oxyanion name ends in -ate, name the acid by adding the suffix -ic to the root.
		If the oxyanion name ends in -ite, name the acid by adding the suffix -ous to the root.
