Comment on "Structural evidence for a dynamic metallocofactor during N2 reduction by Mo-nitrogenase"

Science. 2021 Feb 12;371(6530):eabe5481. doi: 10.1126/science.abe5481.

Abstract

Kang et al (Reports, 19 June 2020, p. 1381) report a structure of the nitrogenase MoFe protein that is interpreted to indicate binding of N2 or an N2-derived species to the active-site FeMo cofactor. Independent refinement of the structure and consideration of biochemical evidence do not support this claim.
