Function

MFNB_METJA Catalyzes the formation of 4-(hydroxymethyl)-2-furancarboxaldehyde phosphate (4-HFC-P) from two molecules of glyceraldehyde-3-P (GA-3-P).[HAMAP-Rule:MF_00681]^[1] ^[2]

Publication Abstract from PubMed

Prior studies have indicated that MJ1099 from Methanocaldococcus jannaschii has roles in the biosynthesis of tetrahydromethanopterin and methanofuran, two key cofactors of one-carbon (C1) metabolism in diverse organisms including the methanogenic archaea. Here, the structure of MJ1099 has been solved to 1.7 A resolution using anomalous scattering methods. The results indicate that MJ1099 is a member of the TIM-barrel superfamily and that it is a homohexamer. Bioinformatic analyses identified a potential active site that is highly conserved among MJ1099 homologs and the key amino acids involved were identified. The results presented here should guide further studies of MJ1099 including mechanistic studies and possibly the development of inhibitors that target the methanogenic archaea in the digestive tracts of humans and that are a source of the greenhouse gas methane.
