Cas links deoxyribose- phosphate by a coordination bond between metal and the phosphategroup.
2
Moreover, no evidence was found for an interaction of either copper species with a phosphategroup or equatorial water molecules.
3
Selective inverse decoupling difference spectroscopy demonstrated that the undecaprenyl phosphategroup is attached to the anomeric carbon of the l-Ara4N unit.
4
A previous study revealed a novel and unexpected interaction between the hydroxyl group of the l-serine substrate and the 5'- phosphategroup of PLP.
5
The phosphategroup interacts with the atoms of the 9-15 loop as well as with NE1 of Trp 57.

1
Only the phosphategroups from the nucleotide take part in metalation.
2
Positively charged metal ions probably act by neutralizing the negatively charged nucleotide phosphategroups.
3
In both complexes the nucleotide is coordinated through phosphategroups.
4
These compounds are linear alpha-1,4-glucans esterified with one or two phosphategroups.
5
This fact has been attributed to changes in the metal-site coordination symmetry because of ligands not involving phosphategroups.
6
On the other hand, the shorter diamine tn in the entire pH range reacts with the phosphategroups from ATP.
7
Enzymatic dephosphorylation and peptide mass analyses demonstrated that the protein contains approximately eight phosphategroups distributed over 30 potential phosphorylation sites.
8
For a low pH value the complexation appears between Cu(II) and ATP molecules via oxygen atoms of phosphategroups.
9
Alkali and alkaline earth metals bind primarily to phosphategroups while transition metals also interact with the N7 of purine bases.
10
At the branch point, two phosphategroups from one helix occupy the major groove of the other one, establishing sequence-specific hydrogen bonds.
11
These chains are then connected to each other via phosphategroups to create a layered network delimiting 6-ring channels trapping rubidium cations.
12
This is supported by the spectra of the phosphate region showing that the phosphategroups of EPA are less hydrogen bonded than DMPA.
13
In particular, the addition of phosphategroups occurs with high frequency on certain serine residues that are located in the cardiac-specific regulatory M domain.
14
An especially striking feature of R. leguminosarum lipid A is that it lacks both the 1- and 4'- phosphategroups.
15
Specific contacts are found between charged lysine and arginine residues and DNA phosphategroups and other binding sites in the minor and major DNA grooves.
16
The phosphategroups and protons form a pH buffer with a pKa of 7.2, which keeps the pH in the synaptic cleft relatively acidic.
