The X-ray crystal structures of SAC and a SAC-carbohydrate conjugate bound to a CA IX-mimic are presented and compared to CA II.
Instead, the crRNAs bind to a different protein called Cas.
Thus, the latter peptides, which have lower affinity for CA (Table 1), may also bind to CA at a site distinct from the hLysRS binding site.
Alternatively, Ca++ could bind to an intracellular elastic "reclosure element" or "release element" in series with the channel, although the nature of these elements is not known [ 36- 38].
Mitf dimers bind to an E-box consensus sequence CA[C/T]GTG in the target promoters to activate the genes (Hemesath et al. 1994; Steingrimsson et al. 1994).
Sp1, which is not present in any of the oligonucleotide/protein complexes, is not expected to bind to these CA repeat sequences and serves as a negative control.
Since CP2 and CP4 bind to WM CA-CTD in a 1 1 stoichiometry even at saturating concentrations, we conclude that site 2 was the primary binding site for the CPs.
This suggested that scFvE2/p17 intrabody and the non-N-myristoylated H6MA-CA protein segregated in separate cellular compartments and that only a small proportion of the scFvE2/p17 molecules could bind to H6MA-CA.
For example, compared with the other 5 antibodies in this group, G45 has a low affinity constant (KD = 12.5 nM) and is not able to inhibit CA activity or bind to bacterially produced CA-GST fusion protein.
"The notion is that minors can't be bound to a contract.
