MF

catalytic activity

Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific b

GO:0003962

MF

cystathionine gamma-synthase activity

Catalysis of the reaction: O-succinyl-L-homoserine + L-cysteine = cystathionine + succinate.

GO:0004123

MF

cystathionine gamma-lyase activity

Catalysis of the reaction: L-cystathionine + H2O = 2-oxobutanoate + L-cysteine + NH4+.

GO:0005737

CC

cytoplasm

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

GO:0005829

CC

cytosol

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

GO:0006520

BP

cellular amino acid metabolic process

The chemical reactions and pathways involving amino acids, carboxylic acids containing one or more amino groups, as carried out by individual cells.

GO:0009970

BP

cellular response to sulfate starvation

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of sulfate.

GO:0018826

MF

methionine gamma-lyase activity

Catalysis of the reaction: L-methionine = methanethiol + NH3 + 2-oxobutanoate.

GO:0019343

BP

cysteine biosynthetic process via cystathionine

The chemical reactions and pathways resulting in the formation of cysteine, via the intermediate cystathionine.

GO:0019346

BP

transsulfuration

The interconversion of homocysteine and cysteine via cystathionine. In contrast with enteric bacteria and mammals, Saccharomyces cerevisiae has two transsulfuration pathways employing two separate sets of enzymes.

GO:0019458

BP

methionine catabolic process via 2-oxobutanoate

The chemical reactions and pathways resulting in the breakdown of methionine, via the intermediate 2-oxobutanoate.

GO:0030170

MF

pyridoxal phosphate binding

Interacting selectively and non-covalently with pyridoxal 5' phosphate, 3-hydroxy-5-(hydroxymethyl)-2-methyl4-pyridine carboxaldehyde 5' phosphate, the biologically active form of vitamin B6.

GO:0042631

BP

cellular response to water deprivation

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of water.

GO:0051289

BP

protein homotetramerization

The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits.

GO:0071266

BP

'de novo' L-methionine biosynthetic process

The chemical reactions and pathways resulting in the formation of L-methionine, the L-enantiomer of (2S)-2-amino-4-(methylsulfanyl)butanoic acid, from simpler components.
