Kang (Reports, 19 June 2020, p. 1381) report a structure of the nitrogenase MoFe protein that is interpreted to indicate binding of N or an N-derived species to the active-site FeMo cofactor. Independent refinement of the structure and consideration of biochemical evidence do not support this claim.
康（Reports，2020 年 6 月 19 日，第 1381 页）报道了一种氮酶 MoFe 蛋白的结构，该结构被解释为表明 N 或 N 衍生物种与活性位点 FeMo 辅因子结合。对结构的独立细化和对生化证据的考虑并不支持这一说法。
