(Kraulis, 1991[Kraulis, P. J. (1991). J. Appl. Cryst. 24,
946-950.]) and RASTER3D (Merritt & Bacon, 1997[Merritt, E. A. &
Bacon, D. J. (1997). Methods. Enzymol. 277, 505-524.]).
Secondary structures are labelled (  1-

5).
The side chains of the catalytic triad (Ser77, Asp133 and
His156) are represented in ball-and-stick. The N- and C-termini
are denoted N and C, respectively.
