Protein attributes
| Sequence length | 640 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level. |
General annotation (Comments)
| Catalytic activity | Succinyl-CoA + glycine = 5-aminolevulinate + CoA + CO2. |
| Cofactor | Pyridoxal phosphate. |
| Pathway | Porphyrin metabolism; protoporphyrin-IX biosynthesis; 5-aminolevulinate from glycine: step 1/1. |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | Mitochondrion matrix By similarity. |
| Miscellaneous | There are two delta-ALA synthetase 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. |
