Isolation and characterization of acid invertase inhibitor from sweet potato. 1976

K Matsushita, and I Uritani

An inhibitor of sweet potato acid invertase [EC 3.2.1.26] was found in fresh sweet potato root tissue, and partially purified. The inhibitor is possibly a thermostable protein with a molecular weight of about 19,500. The inhibitory activity is highly specific to acid invertase. The inhibitor binds to the enzyme reversibly in a non-competitive way, inhibiting the enzyme activity.

UI	MeSH Term	Description	Entries
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant
D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D004791	Enzyme Inhibitors	Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.	Enzyme Inhibitor,Inhibitor, Enzyme,Inhibitors, Enzyme
D013393	Sucrase	Digestive enzyme secreted in the INTESTINES. It catalyzes hydrolysis of SUCROSE to FRUCTOSE and GLUCOSE.	Mutansucrase,Sucrose alpha-D-Glucohydrolase,Sucrose alpha D Glucohydrolase,alpha-D-Glucohydrolase, Sucrose
D013696	Temperature	The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms.	Temperatures
