Significats de phosphate groups en anglès

Only the phosphate groups from the nucleotide take part in metalation.

Positively charged metal ions probably act by neutralizing the negatively charged nucleotide phosphate groups.

In both complexes the nucleotide is coordinated through phosphate groups.

These compounds are linear alpha-1,4-glucans esterified with one or two phosphate groups.

This fact has been attributed to changes in the metal-site coordination symmetry because of ligands not involving phosphate groups.

On the other hand, the shorter diamine tn in the entire pH range reacts with the phosphate groups from ATP.

Enzymatic dephosphorylation and peptide mass analyses demonstrated that the protein contains approximately eight phosphate groups distributed over 30 potential phosphorylation sites.

For a low pH value the complexation appears between Cu(II) and ATP molecules via oxygen atoms of phosphate groups.

Alkali and alkaline earth metals bind primarily to phosphate groups while transition metals also interact with the N7 of purine bases.

At the branch point, two phosphate groups from one helix occupy the major groove of the other one, establishing sequence-specific hydrogen bonds.

These chains are then connected to each other via phosphate groups to create a layered network delimiting 6-ring channels trapping rubidium cations.

This is supported by the spectra of the phosphate region showing that the phosphate groups of EPA are less hydrogen bonded than DMPA.

In particular, the addition of phosphate groups occurs with high frequency on certain serine residues that are located in the cardiac-specific regulatory M domain.

An especially striking feature of R. leguminosarum lipid A is that it lacks both the 1- and 4'- phosphate groups.

Specific contacts are found between charged lysine and arginine residues and DNA phosphate groups and other binding sites in the minor and major DNA grooves.

The phosphate groups and protons form a pH buffer with a pKa of 7.2, which keeps the pH in the synaptic cleft relatively acidic.
