Polysaccharide lyases

Applied Biochemistry and Biotechnology, 1987
Polysaccharide lyases (or eliminases) are a class of enzymes (EC 4.2.2.-) that act to cleave certain activated glycosidic linkages present in acidic polysaccharides. These enzymes act through an eliminase mechanism, rather than through hydrolysis, resulting in unsaturated oligosaccharide products.

Adenylosuccinate lyase deficiency

Molecular Genetics and Metabolism, 2006
Adenylosuccinate lyase deficiency is a disease of purine metabolism which affects patients both biochemically and behaviorally. The symptoms are variable and include psychomotor retardation, autistic features, hypotonia, and seizures. Patients also accumulate the substrates of ADSL in body fluids.

Selenocysteine Lyase

EcoSal Plus, 2004
Selenocysteine is a naturally occurring analog of cysteine in which the sulfur atom of the latter is replaced with selenium. This seleno-amino acid occurs as a specific component of various selenoproteins and selenium-dependent enzymes.

Structure and mechanism of tryptophan indole-lyase and tyrosine phenol-lyase

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2003
Tyrosine phenol-lyase (TPL) and tryptophan indole-lyase (Trpase) catalyse the reversible hydrolytic cleavage of L-tyrosine or L-tryptophan to phenol or indole, respectively, and ammonium pyruvate. These enzymes are very similar in sequence and structure, but show strict specificity for their respective physiological substrates.

Spatial structure and the mechanism of tyrosine phenol-lyase and tryptophan indole-lyase

Molecular Biology, 2009
The bacterial tyrosine phenol-lyase (EC 4.1.99.2) and tryptoptophan indole-lyase (EC 4.1.99.1) belong to pyridoxal-5'-phosphate dependent beta-eliminating lyases, catalysing the reversible decomposition of L-tyrosine and L-tryptophan to pyruvate, ammonia, and phenol or indole correspondingly.
