Chains	Enzyme Name	Description	Catalytic Residues
A	S-(hydroxymethyl)glutathione synthase M-CSA #712	Glutathione-dependent formaldehyde-activating enzyme (Gfa) is a carbon-sulphur lyase enzyme that catalyses the first step of a pathway that metabolises toxic formaldehyde to yield formate as a product. Gfa catalyses the condensation of formaledhyde and glutathione to form an adduct, S-hydroxymethylglutathione.
