| In [[enzymology]], an '''ethanolamine-phosphate phospho-lyase''' ({{EC number|4.2.3.2}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]
| |
| | |
| :ethanolamine phosphate + H<sub>2</sub>O <math>\rightleftharpoons</math> acetaldehyde + NH<sub>3</sub> + phosphate
| |
| | |
| Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[ethanolamine phosphate]] and [[water|H<sub>2</sub>O]], whereas its 3 [[product (chemistry)|products]] are [[acetaldehyde]], [[ammonia|NH<sub>3</sub>]], and [[phosphate]].
| |
| | |
| This enzyme belongs to the family of [[lyase]]s, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is '''ethanolamine-phosphate phosphate-lyase (deaminating acetaldehyde-forming)'''. Other names in common use include '''O-phosphoethanolamine-phospholyase''', '''amino alcohol O-phosphate phospholyase''', '''O-phosphorylethanol-amine phospho-lyase''', and '''ethanolamine-phosphate phospho-lyase (deaminating)'''. It employs one [[cofactor (biochemistry)|cofactor]], [[pyridoxal phosphate]].
