Hyaluronidase HylPl

The arcs most typical of TS /1-solenoids differ in conformation and consensus sequence from those of single-stranded /1-solenoids (Hennetin et al., 2006). This difference may originate in the fact that each chain of a TS /1-solenoid has an axial rise of 14.5 A as opposed to 4.8 A. On the other hand, the inverted arcs of the TS /1-solenoid from hyaluronidase HylPl (Smith et al., 2005) have ( -conformations, like those found in single-stranded /1-solenoids (Hennetin et al., 2006). Neither the /1-strands nor the /1-arcs of TS /l-solenoids contain proline, while the long loops frequently contain this residue.
