EC Number Protein Variants Comment Organism
4.6.1.2 I145Y substitution in the full-length beta-subunit of the sGC heterodimer, does not produce an oxygen-binding enzyme, but impedes the association of NO and destabilizes the NO-heme complex. The tyrosine in the distal heme pocket impedes both the binding and dissociation of the CO ligand. Mutation does not affect stimulatory effect of manganese ion on the activity of the enzyme, thus function of the catalytic domain is not directly affected Caldanaerobacter subterraneus subsp. tengcongensis
