4.3.1.17 L-serine ammonia-lyaseIUBMB Comments
Most enzymes that catalyse this reaction are pyridoxal-phosphate-dependent, although some enzymes contain an iron-sulfur cluster instead . The reaction catalysed by both types of enzymes involves the initial elimination of water to form an enamine intermediate (hence the enzyme's original classification as EC 4.2.1.13, L-serine dehydratase), followed by tautomerization to an imine form and hydrolysis of the C-N bond. The latter reaction, which can occur spontaneously, is also be catalysed by EC 3.5.99.10, 2-iminobutanoate/2-iminopropanoate deaminase. This reaction is also carried out by EC 4.3.1.19, threonine ammonia-lyase, from a number of sources.

L-serine = pyruvate + NH3
A pyridoxal-phosphate protein. This reaction is also carried out by EC 4.3.1.19 threonine ammonia-lyase, from a number of sources. The reaction catalysed probably involves initial elimination of water, hence the enzyme's original classification as EC 4.2.1.13, L-serine dehydratase, followed by isomerization and hydrolysis of the product with C-N bond breakage
-
-
L-serine = pyruvate + NH3
reaction analysis by ab initio quantum mechanical/molecular mechanical method, the reaction involves a Schiff base formation step and a proton-relaying mechanism involving the phosphate of the cofactor in the beta-hydroxyl-leaving step following sequentially after the elimination of the alpha-proton, leading to a single but sequential alpha,beta-elimination step. The rate-limiting transition state is specifically stabilized by the enzyme environment, catalytic mechanism involving Lys41 in the active site, detailed overview
L-serine = pyruvate + NH3
pre-steady-state kinetic analysis of L-serine binding to lpLSD demonstrates that L-serine binds to a second noncatalytic site and produces a conformational change in the enzyme. The rate of this conformational change is too slow for its participation in the catalytic cycle but rather occurs prior to catalysis to produce an activated form of the enzyme

L-serine ammonia-lyase (pyruvate-forming)
Most enzymes that catalyse this reaction are pyridoxal-phosphate-dependent, although some enzymes contain an iron-sulfur cluster instead [6].

4Fe-4S-center
the enzyme contains a [4Fe-4S]2+ cluster that acts as a Lewis acid to extract the hydroxyl group of L-serine during the dehydration reaction. Fe-S cluster binding induces protein conformational changes in L-serine dehydratase. All four iron atoms of the [4Fe-4S] cluster are coordinated with protein cysteine residues (C396, C485, C343, C385). formation of disulfide bonds between C396 and C485 and possibly between C343 and C385

physiological function
physiological function
Escherichia coli K-12 provided with glucose and a mixture of amino acids depletes L-serine more quickly than any other amino acid even in the presence of ammonium sulfate. A mutant lacking 4Fe4S L-serine deaminases SdaA, SdaB, and TdcG is unable to do this. The high level of L-serine that accumulates when the mutant is exposed to amino acid mixtures starves the cells for C1 units and interferes with cell wall synthesis. Growth in minimal medium containing glucose, ammonium sulfate, and Casamino Acids results in deformed cells and frequently lysing, which can be reversed by adding S-adenosylmethionine
physiological function
