General annotation (Comments)

Catalytic activity

Succinyl-CoA + glycine = 5-aminolevulinate + CoA + CO2.

Cofactor

Pyridoxal phosphate.

Pathway

Porphyrin-containing compound metabolism; protoporphyrin-IX biosynthesis; 5-aminolevulinate from glycine: step 1/1.

Subunit structure

Homodimer By similarity.

Subcellular location

Mitochondrion matrix.

Miscellaneous

There are two delta-ALA synthases in vertebrates: an erythroid- specific form and one (housekeeping) which is expressed in all tissues.

Sequence similarities

Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family.
