Protein attributes

Sequence length	358 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Involved in the biosynthesis of tyrosine. Has a weak prephenate dehydrogenase activity. Ref.5
Catalytic activity	L-arogenate + NADP+ = L-tyrosine + NADPH + CO2.
Pathway	Amino-acid biosynthesis; L-tyrosine biosynthesis; L-tyrosine from L-arogenate: step 1/1.
Subcellular location	Plastid › chloroplast.
Tissue specificity	Expressed in roots, stems, leaves, flowers, siliques and seeds. More abundant in seeds.
Induction	Strongly inhibited by tyrosine.
Miscellaneous	Unlike TYRAAT1, TYRAAT2 is composed of a single catalytically active domain.
Sequence similarities	Contains 1 prephenate/arogenate dehydrogenase domain.
biophysicochemical properties	Kinetic parameters: NADP increases the apparent affinity for arogenate. KM=14.3 µM for NADP KM=84.2 µM for arogenate KM=17000 µM for prephenate Vmax=73 µmol/min/mg enzyme
