Function
ACEA_MYCTU Catalyzes the formation of succinate and glyoxylate from isocitrate, a key step of the glyoxylate cycle. May be involved in the assimilation of one-carbon compounds via the isocitrate lyase-positive serine pathway (By similarity).
Publication Abstract from PubMed
We report the unprecedented reaction between a nitroalkane and an active-site cysteine residue to yield a thiohydroximate adduct. Structural and kinetic evidence suggests the nitro group is activated by conversion to its nitronic acid tautomer within the active site. The nitro group, therefore, shows promise as a masked electrophile in the design of covalent inhibitors targeting binding pockets with appropriately placed cysteine and general acid residues.
