diffraction structural biology
Diffraction data to 3.2 Å from crystals of the 3.6 MDa erythrocruorin from a Brazilian earthworm represent the highest resolution reported to date for similar complexes. An unambiguous molecular replacement solution shows the particle to belong to the type I class.
diffraction structural biology
A binary complex between a low-molecular-weight purine nucleoside phosphorylase and ribose-1-phosphate is described for the first time and comparisons with known ternary complexes are drawn.
