Secondary Structure of Integrases Structures determined by the Macromolecular Crystallography Laboratory , Protein Structure Section at the NCI-Frederick campus. Work performed in collaboration with the Skalka Laboratory in the Institute for Cancer Research , Fox Chase Cancer Center . Many sequences can fold into similar secondary structures, which is often the case for different proteins that perform similar jobs on various targets. Secondary structure also comprises the placement of specific amino acids and how they interact with metal cations , other molecules , or inhibitors .
Proteins have helices as well, shown as the tight yellow and brown spirals.
Strands are extended lengths of amino acids, shown as flat blue and green ribbons. The black dot just to the left of center marks the position of the active site . Back to the ASV IN home page.
