Taxonomic lineage

Eukaryota › Metazoa › Arthropoda › Hexapoda › Insecta › Pterygota › Neoptera › Endopterygota › Diptera › Brachycera › Muscomorpha › Ephydroidea › Drosophilidae › Drosophila › Sophophora

Protein attributes

Sequence length	270 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Catalyzes the last step in the biosynthesis of serine from carbohydrates. The reaction mechanism proceeds via the formation of a phosphoryl-enzyme intermediates By similarity.
Catalytic activity	O-phospho-L(or D)-serine + H2O = L(or D)-serine + phosphate.
Cofactor	Magnesium By similarity.
Pathway	Amino-acid biosynthesis; L-serine biosynthesis; L-serine from 3-phospho-D-glycerate: step 3/3.
Developmental stage	Expressed in a complex banded pattern early in embryogenesis. During maturation of the embryo, expression becomes restricted to cells around and of the gut. Ref.1
Sequence similarities	Belongs to the serB family.
