Organism

Escherichia coli (strain K12) [Complete proteome] [HAMAP]

Taxonomic identifier

83333 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia

Protein attributes

Sequence length	454 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Deaminates also threonine, particularly when it is present in high concentration.
Catalytic activity	L-serine = pyruvate + NH3.
Cofactor	Binds 1 4Fe-4S cluster Probable.
Pathway	Carbohydrate biosynthesis; gluconeogenesis.
Induction	It is made aerobically and anaerobically, in minimal medium.
Post-translational modification	Activated by post-translational modification by a system involving at least three gene products. Activation is mimicked in vitro by iron and dithiothreitol. There is considerable evidence for a free-radical activation mechanism.
Sequence similarities	Belongs to the iron-sulfur dependent L-serine dehydratase family.
