Fold: L28p-like

unusual fold consisting of three beta-hairpins, that form a paper clip-like structure, and two helices; could have evolved from a glucocorticoid receptor-like zinc finger domain (scop_cf 57715)

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: L28p-like [143799]
    unusual fold consisting of three beta-hairpins, that form a paper clip-like structure, and two helices; could have evolved from a glucocorticoid receptor-like zinc finger domain (scop_cf 57715)

Superfamilies:

  1. L28p-like [143800] (2)
    In early ribosomal structures, L28p has been misinterpreted as L31p. in the Ribosomal protein L28p family, there are sequences containing two CxxC pairs. Threading these sequences into this fold brings the four cysteines in a similar site to the zinc-binding site of glucocorticoid receptor-like zinc fingers. In the Ribosomal protein L31p, there are also members with two CxxC pairs. However, these won't form a putative zinc-binding site in this fold. The L31p family are classified here temporarily, until its true fold is known
