ID   4.3.1.17
DE   L-serine ammonia-lyase.
AN   L-hydroxyaminoacid dehydratase.
AN   L-serine deaminase.
AN   L-serine dehydratase.
AN   L-serine hydro-lyase (deaminating).
AN   serine deaminase.
CA   L-serine = NH4(+) + pyruvate.
CC   -!- The reaction catalyzed by both types of enzymes involves the initial
CC       elimination of water to form an enamine intermediate (hence the
CC       enzyme's original classification as EC 4.2.1.13) followed by
CC       tautomerization to an imine form and hydrolysis of the C-N bond.
CC   -!- The latter reaction, which can occur spontaneously, is also be
CC       catalyzed by EC 3.5.99.10.
CC   -!- This reaction is also carried out by EC 4.3.1.19 from a number of
CC       sources.
CC   -!- Formerly EC 4.2.1.13.
