| Function | Specifically catalyzes the decarboxylation of meso-diaminopimelate (meso-DAP) to L-lysine. |
| Catalytic activity | RHEA:15101: H(+) + meso-2,6-diaminoheptanedioate = CO2 + L-lysine
EC 4.1.1.20 |
| Cofactor | pyridoxal 5'-phosphate |
| Pathway | Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; L-lysine from DL-2,6-diaminopimelate: step 1/1. |
| Subunit | Homodimer. |
| Similarity | Belongs to the Orn/Lys/Arg decarboxylase class-II family. LysA subfamily. |
