At rest, the myosin head is bound to an ATP molecule in a low-energy configuration and is unable to access the cross bridge binding sites on the actin.

However, the heterogeneous nature of sheared DNA fragments maps binding sites to within 300 base pairs, limiting specificity.

Because transcription factors can bind a set of related sequences and these sequences tend to be short, potential transcription factor binding sites can occur by chance if the DNA sequence is long enough.

There were also several sites that appear to be the general transcription factor TFIIB, and both E2F and E2F transcription factor binding sites.

Forty-three transcription factor binding sites were compiled from the literature (see [ 14] for a complete list of sequences).

The current version of AGRIS contains only 5' promoter regions, binding sites have also been identified in 3' regions and introns, but they are limited in number and for the time being not represented.

The standard serum attacks binding sites.

It then bound the stadiums, halls and other sites to long-term exclusive contracts that kept rivals out in the cold.

More complex HigherLevelAnalyses might include predictions of gene function, experiment class (for example, tumor classification), or associated regulatory sequences (transcription factor binding sites).

Calcium binds to AdPLA and forms a positively charged oxyanion hole to stabilize a negatively charged transition state, similar to other PLA2 active sites.
