Invertase from Hyper Producer Strain of Aspergillus niger: Physiochemical Properties, Thermodynamics and Active Site Residues Heat of Ionization

Here we report for the first time heat of ionization of invertase (E.C.3.2.1.26) active site residues from hyperproducer strain of Aspergillus niger (34.1 U ml-1), along with its physiochemical properties, kinetics and thermodynamics of stability-function. The Invertase showed great potential for industry as being highly efficient (kcat = 24167 s-1 at 65 °C, pH 5.0) and stable (half life= 12 h at 56°C).
