Definition
English
:
A multifunctional
pyridoxal phosphate
enzyme. In the second stage of
cysteine
biosynthesis it catalyzes the reaction of
homocysteine
with
serine
to form
cystathionine
with the elimination of water. Deficiency of this enzyme leads to
HYPERHOMOCYSTEINEMIA
and
HOMOCYSTINURIA
. EC 4.2.1.22.
