Beta solenoid

Indian businessman

A beta solenoid is a protein fold composed of repeating beta strands subunits, arranged in antiparallel fashion to form a superhelix.

Terminology and classification

Beta solenoids are part of the solenoid class of protein tandem repeats.

Structure

Beta solenoids are elongated and potentially open-ended protein repeats characterized by beta strands winding around an imaginary axis, where the beta sheets are formed by sequences of consecutive repeat units.[1]
