mergefrom Winged helix turn helix discuss Talk Helix turn helix Merger proposal date October 2011 Image Lambda repressor 1LMB.png 200px thumb The &lambda repressor of bacteriophage lambda employs a helix turn helix left green to bind DNA right blue and red . In protein s, the helix turn helix HTH is a major structural motif capable of binding DNA . It is composed of two alpha helix helices joined by a short strand of amino acid s and is found in many proteins that regulate gene expression . It should not be confused with the helix loop helix domain. Its discovery was based on similarities between the genes for Cro, Catabolite activator protein CAP , and cI protein repressor , which share a common 20 25 amino acid sequence that facilitates DNA recognition. In particular, recognition and binding to DNA is done by the two helices, one occupying the N terminus N terminal end of the motif, the other at the C terminus . In most cases, such as in the Cro repressor, the second helix contributes most to DNA recognition, and hence it is often called the recognition helix . It binds to the major groove of DNA through a series of hydrogen bond s and various Van der Waals bonding Van der Waals interactions with exposed base pair bases . The other helix stabilizes the interaction between protein and DNA, but does not play a particularly strong role in its recognition.

unreferenced date June 2011 A helix building is a small structure at the base of a longwave or mediumwave radio transmitter . Within, there are capacitor s and Inductor coil s for coupling the signal from the feed cable to the Antenna radio antenna . Active components such as amplifier s are usually not housed in a helix building. The interior of the helix building is typically covered with copper or aluminium, in order to control stray radiation. For safety, helix buildings must be secured, due to the dangerously high voltages which may be present inside. The helix building, which may be a simple switchbox for small transmitters, is sometimes also the base of a mast radiator .

The finished development will be an outdoor recreational area open to all, offering easy access to picturesque woodland, a central park with a lagoon, linked walking paths and cycleways. It will also open up the Forth and Clyde Canal by installing a new full length canal link and a canal hub featuring two unique equine structures known as the Kelpies. Each structure will measure around 30 metres in height. The Kelpies are the brainchild of Andy Scott sculptor Andy Scott who also created the Heavy Horse sculpture at the side of the M8 motorway Scotland M8 motorway between Glasgow and Edinburgh . Another inspiration was the fact that Carnera , the UK s largest Clydesdale horse Clydesdale Horse , once resided in Falkirk. Project Background The Helix has been awarded a 25 million grant by The Big Lottery Fund as part of its Living Landmarks Programme. Significant funding and land has also been committed by Falkirk Council and British Waterways Scotland. The project is being driven by a partnership of Falkirk Council, British Waterways Scotland and Central Scotland Forest Trust through the Helix Trust.
