FIG 1.
(A) CMY-2 and CMY-33 model (blue) molecular structure superimposi tion. (B) Magnification of the H-10 helix in CMY-2 and CMY-33. The deletion (Leu293-Ala294) in the CMY-33 enzyme increases the distance from Ser64 to the H-10 helix by ~4 Å (from 7.8 to 11.6 Å), changing the shape, size, and possibly the flexibility of the active site.
