Medchemexpress LLC Formaldehyde dehydrogenase, Pseudomonas sp | 9028-84-6 | 5 U
Formaldehyde dehydrogenase is a widely occurring enzyme that catalyzes S-hydroxymethylglutathione in the presence of NAD. It detoxifies formaldehyde within cells by capturing and limiting it from reaching a toxic level. This enzyme can be studied in research on *M. tuberculosis*. It appears as a solid, white to off-white in color.
- Catalyzes S-hydroxymethylglutathione in the presence of NAD
- Detoxifies formaldehyde within cells by limiting toxic levels
- Valuable for research on *M. tuberculosis*
- White to off-white solid appearance
- Activity loss of ≤10% after 7 days at 37°C (powder)
- Activity inhibited by N2+, Pd2+, Hg2+, 4-chloromercuric benzoic acid, and fluorophenylmethylsulfonyl
- Easily soluble in water, but solution is unstable and should be prepared for immediate use
- Optimum pH is 7.3-7.6
- Reversible inactivation at pH 5.0, irreversible inactivation above pH 9.0
