Biochemistry, 31, pp. 8009 - 8021, 1992.

Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 38.76   b = 40.06   c = 33.73 (Ångstroms)

α = 90.0   β = 90.0   γ = 90.0 (degrees)

Refinement:

The structure was refined using the NUCLSQ program. The R value is 0.178 for 3683 reflections in the resolution range 8.0 to 1.7 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
