functional role of the mobile beta2alpha2 loop, especially of loop residues H98 and W99, analysis by site-directed mutagenesis, isothermal titration calorimetry, saturation transfer difference NMR spectroscopy, and molecular dynamics simulation, three-dimensional structure of the enzyme and its active site, overview
additional information
-
the catalytic domain is a five-bladed beta-propeller consisting of five radially oriented anti-parallel beta-sheets, substrate binding at five subsites in the catalytic cleft and an L-arabinose-binding pocket at the bottom of the cleft. Asp202 and Glu361 are catalytic residues, and Trp270, Tyr461, and Asn462 are involved in the substrate-binding site for discriminating the substrate structures
additional information
tight domain associations found in the enzyme, such as an interdomain disulfide bond (Cys306 and Cys476) in each monomer, an extended arm (amino acids 374-385) at the dimer interface, and total 12 salt bridges in the hexamer, may account for the thermostability of the enzyme. One of the xylan binding determinants (Trp96) is identified in the active site, and a region of amino acids (374-385) protrudes out forming an obvious wall at the substrate-binding groove to generate a cavity. The altered cavity shape with a strong negative electrostatic distribution is likely related to the unique substrate preference of TmAFase towards branched polymeric substrates
