GFA - A Glutathione-Dependent Formaldehyde-Activating Enzyme
Basic Description
An enzyme from Paracoccus denitrificans that accelerates this spontaneous condensation reaction, which catalyze the conversion of formaldehyde and glutathione was purified and named glutathione-dependent formaldehyde-activating enzyme (Gfa).
The gene GFA is located directly upstream of the gene for glutathione-dependent formaldehyde dehydrogenase, which catalyzes the subsequent oxidation of S-hydroxymethylglutathione. The glutathione-dependent formaldehyde conversion to formate starts with the adduct formation, formaldehyde reacts with the SH group of glutathione producing S-hydroxymethylglutathione (Reaction 1).

Formaldehyde-converting enzymes-Gfa is composed of one type of subunit of about 20 kDa and lack a chromophoric prosthetic group. In addition, both enzymes are encoded next to genes for enzymes involved in further oxidation of the cofactor-bound one-carbon unit to carbon dioxide.

Sequence
We ordered the synthesized plasmid from Genscript. After restriction digestion & transformation, we got our E. coli with GFA.
