| polyoxyethylene-superoxide dismutase | <chemical> Recombinant human cu,zn superoxide dismutase with polyoxyethylene; decreases side effects of superoxide-generating antineoplastics such as adriamycin and mitomycin c Synonym: sod-poe, poe-sod, polyoxyethylene-modified superoxide dismutase (26 Jun 1999) |
| hydroxylamine dismutase | <enzyme> From extracts of phototropic cultures of phormidium uncinatum; catalyses formation of nitrite and ammonia from h2o2 and nh2oh Registry number: EC 1.7.99.- (26 Jun 1999) |
| superoxide dismutase | <enzyme> Any of a range of metalloenzymes that catalyses the formation of hydrogen peroxide and oxygen from superoxide and thus protects against superoxide induced damage. Usually has either iron or manganese as the metal cation in prokaryotes, copper or zinc in eukaryotes. (18 Nov 1997) |
| dismutase | Generic name for enzymes catalyzing the reaction of two identical molecules to produce two molecules in differing states of oxidation (e.g., superoxide dismutase) or of phosphorylation (e.g., glucose 1-phosphate phosphodismutase). (05 Mar 2000) |
| active formaldehyde | A hydroxymethyl derivative of tetrahydrofolate or thiamin pyrophosphate, N5,N10-methylenetetrahydrofo late. (05 Mar 2000) |
| melamine formaldehyde | A plastic material mixed with plaster of Paris for casts. Such a cast is lighter and stronger than one made with plaster of Paris alone. Synonym: melamine formaldehyde. (05 Mar 2000) |
| mycothiol-dependent formaldehyde dehydrogenase | <enzyme> Registry number: EC 1.2.1.- Synonym: mdf dehydrogenase (26 Jun 1999) |
| formaldehyde | <chemical> Commonly used fixative and antibacterial agent. As a fixative it is cheap and tends to cause less denaturation of proteins than does glutaraldehyde, particularly if used in a well buffered solution (buffered formalin, formal saline). Old formaldehyde solutions usually contain cross linking contaminants and it is therefore often preferable to used a formaldehyde generating agent such as paraformaldehyde. Formalin fumes, particularly in conjunction with hydrochloric acid vapour, are potently carcinogenic. (20 Jun 2000) |
| formaldehyde ferredoxin oxidoreductase | <enzyme> Contains molybdopterin as the organic component of tungsten cofactor Registry number: EC 1.2.7.- Synonym: hcho ferredoxin oxidoreductase (26 Jun 1999) |
| formaldehyde fixative | A widely used fixing agent for pathologic histology; the commercial solution is 37-40% formaldehyde and is known as 100% formalin or formol; a common impurity is formic acid, which must be neutralised or the fixative made in buffer solution; tissues fixed may have a pigment artifact precipitated.

| formaldehyde reductase | <enzyme> Catalyses reduction of formaldehyde to methanol using NADH Registry number: EC 1.1.1.- (26 Jun 1999) |
| formaldehyde transketolase | <enzyme> From yeast; formaldehyde plus xylulose-5-phosphate yields glyceraldehydephosphate and dihydroxyacetone Registry number: EC 2.2.1.3 Synonym: dihydroxyacetone synthase (26 Jun 1999) |
