There are 26 mile of hiking trails at Ricketts Glen State Park, and a 12.5 mile trail loop is open for horseback riding.
The hydrogen bonding pattern of this loop (residues 153 160) in the open and closed conformations suggested that the loop is open in the absence of bound ligand, which enables the substrate (or inhibitor) to enter the active site.
When the trigger loop is open, the secondary pore provides a route to solvent.
When PMP is present at the active site, the loop is open, thus allowing substrate entry and product release.
In the ADP bound structure, the C-tail is disordered, the Gly-rich loop is open, and the two motifs are not coupled.
In protomer A of the wild-type DHQD complex with shikimate, the β8−α8 loop is open and Arg213 adopts its unliganded conformation.
All four NPs have an aspartic acid as the last residue of β-strand A, and for NP4, Asp30 is believed to be the major factor that determines whether the A B loop is open or closed.
If, however, the observer is asked to adjust a variable prism according to his or her comfort, the fusional feedback loop is open and cannot stabilize the vergence angle.
In the NP4 V36A/D129A/L130A -NO structure (pH 5.6), which has mutatioNP4 V36A/D129A/L130A -NO(Val36) and the G–H loop (Astructure Leu130), the G–H loopHis open and density for the A–B loop is nearly nonexistent, as expected.
At high temperatures (>1000 °C), the stress strain loops are open, the response is strain rate dependent and cyclic hardening is observed for both microstructures.
