Heparin, therefore, also acts as a template for binding of both protease and serpin, further dramatically accelerating the interaction between the two parties (Figure 7).
6S RNA acts as a template for binding of σ, and is thus capable, when upregulated, of titrating σ thus leading to downregulation of genes under σ control.
This complex binding mode may explain the lower than expected significance of SMAP hits for known H3P targets, as the template for the binding site used for the SMAP screen did not capture the six-molecule ring binding mode.
In marked contrast to β2-tryptase, the Ser214-Gly219 segment, which normally provides the template for substrate binding, is kinked in α-tryptase, thereby blocking its non-primed subsites.
R. prowazekii has been shown to utilize regulated promoters and to organize genes into operons [4], [5], [6], [7], [8], [9], and rickettsial RNA polymerase was shown to exhibit properties that distinguish it from the Escherichia coli polymerase, such as the requirement for a supercoiled template for promoter binding, [10], [11].
The most similar member of the larger superfamily is UDP-galactose 4-epimerase [14] (PDB entry 1KVQ), which provided a template for the binding modes of both the nicotinamide cofactor and substrate in the earlier structural analyses of the apo-forms of IFR, PCBER and PLR [6], [7].
This is considered to be a ligand-bound structure and therefore is an appropriate template for ligand binding studies.
Much of the relevant chemistry, including the template for the binding of oxygen at CuM and the state of CuH immediately prior to ET, occurs in the Cu(I) state that is opaque to many traditional spectroscopic methods because of its d configuration.
First it creates CMepGs (which can serve as templates for methyl binding proteins), and second, it eliminates CUn-MepGs (which are the binding sites of various CXXC proteins).
The present study reports the development of a template for the active binding site of Cdk5 for structure-based drug design.
Previously reported structures of the N-terminal domain of the Siglec sialoadhesin (SnD1) in complex with various sialic acid analogs revealed the structural template for sialic acid binding.
