The dinuclear ironânitrosyl complex [Fe2(SMe)2(NO)4] has been isolated from reactions of iron(II) salts and sodium nitrite with methionine, under reaction conditions relevant to food processing.

The dinuclear iron-nitrosyl complex [Fe2(SMe)2(NO)4] can be isolated from reactions between methionine and iron(II) sulphate or chloride in the presence of sodium nitrite, under a range of experimental conditions; the analogous complex [Fe2(SEt)2(NO)4] is formed in similar reactions using ethionine in place of methionine. Spectroscopic evidence supports the formation of similar dinuclear complexes [Fe2(SR)2NO)4], as well as the tetranuclear [Fe4S3(NO)7] in reactions between iron(II), nitrite and certain cysteine and penicillamine derivatives.

Rational redesign of bacterialS-adenosylmethionine-synthase by 3D-modelling and docking led to variants that allow synthesis of methylation cofactor SAM (AdoMet) without product inhibition, and of higher alkyl homologues.
