In [[enzymology]], a '''tryptophan alpha,beta-oxidase''' ({{EC number|1.3.3.10}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:L-tryptophan + O<sub>2</sub> <math>\rightleftharpoons</math> alpha,beta-didehydrotryptophan + H<sub>2</sub>O<sub>2</sub>

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[L-tryptophan]] and [[oxygen|O<sub>2</sub>]], whereas its two [[product (chemistry)|products]] are [[alpha,beta-didehydrotryptophan]] and [[hydrogen peroxide|H<sub>2</sub>O<sub>2</sub>]].

This enzyme belongs to the family of [[oxidoreductase]]s, specifically those acting on the CH-CH group of donor with oxygen as acceptor.  The systematic name of this enzyme class is '''L-tryptophan:oxygen alpha,beta-oxidoreductase'''. Other names in common use include '''L-tryptophan 2',3'-oxidase''', and '''L-tryptophan alpha,beta-dehydrogenase'''.  It employs one [[cofactor (biochemistry)|cofactor]], [[heme]].
