CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-serine = NH4(+) + pyruvate; Xref=Rhea:RHEA:19169,
CC         ChEBI:CHEBI:15361, ChEBI:CHEBI:28938, ChEBI:CHEBI:33384; EC=4.3.1.17;
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000250};
CC   -!- PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the serine/threonine dehydratase family.
CC       {ECO:0000305}.
CC   -!- CAUTION: Could be the product of a pseudogene unlikely to encode a
CC       functional protein. This is a truncated version of L-serine
CC       dehydratase. Strain S288c has a stop codon in position 128, which
CC       disrupts the gene coding for this protein and produces two ORFs YIL167W
CC       and YIL168W. Because of that it is not part of the S.cerevisiae S288c
CC       complete/reference proteome set. A contiguous sequence for L-serine
CC       dehydratase can be found in other strain backgrounds (AC P0CF23).
