The Streptococcus pyogenes cell-surface protein Scl2 contains a globular N-terminal domain and a collagen-like domain, (Gly-Xaa-X'aa)(79), which forms a triple helix with a thermal stability close to that seen for mammalian collagens. Hyp is a major contributor to triple-helix stability in animal collagens, but is not present in bacteria, which lack prolyl hydroxylase. To explore the basis of bacterial collagen triple-helix stability in the absence of Hyp, biophysical studies were carried out… CONTINUE READING
