THE REMARK 400 FRU-2,6-BISPHOSPHATASE IS C-TERMINAL HALF REMARK 400 (RESIDUE 251-470) OF THE BIFUNCTIONAL REMARK 400 6-PHOSPHOFRUCTO-2-KINASE/FRU-2,6-BISPHOSPHATASE REMARK 400 (470 AMINO ACIDS). THE STRUCTURE PRESENTED HERE IS FROM REMARK 400 THE CLONE WHICH COVERS THE CORE BISPHOSPHATASE DOMAIN REMARK 400 (RESIDUES 251-440) OF THE BIFUNCTIONAL ENZYME. THE REMARK 400 STRUCTURE WAS DETERMINED BY MAD PHASING WHERE THE MAD REMARK 400 DATA FROM THE SELENOMETHIONINE-LABELLED BISPHOSPHATASE REMARK 400 WERE TREATED FOR MIR-STYLE PHASE CALCULATION. A REMARK 400 COMPETITIVE INHIBITOR, PHOSPHATE, WAS USED FOR THE REMARK 400 CRYSTALLIZATION BUFFER. THE PRESENCE OF PI IN THE REMARK 400 PROTEIN STRUCTURE WAS USED TO IDENTIFY THE ACTIVE SITE.
