Bacteria › Proteobacteria › Gammaproteobacteria › Pseudomonadales › Moraxellaceae › Psychrobacter

Protein attributes

Sequence length	339 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes both the ATP-dependent activation of exogenously supplied lipoate to lipoyl-AMP and the transfer of the activated lipoyl onto the lipoyl domains of lipoate-dependent enzymes By similarity. HAMAP MF_01602
Catalytic activity	ATP + lipoate = diphosphate + lipoyl-AMP. HAMAP MF_01602 Lipoyl-AMP + protein = protein N(6)-(lipoyl)lysine + AMP. HAMAP MF_01602
Pathway	Protein modification; protein lipoylation via exogenous pathway; protein N(6)-(lipoyl)lysine from lipoate: step 1/2. HAMAP MF_01602 Protein modification; protein lipoylation via exogenous pathway; protein N(6)-(lipoyl)lysine from lipoate: step 2/2.
Subunit structure	Monomer By similarity. HAMAP MF_01602
Subcellular location	Cytoplasm By similarity HAMAP MF_01602.
Miscellaneous	In the transfer reaction, the free carboxyl group of lipoic acid is attached via an amide linkage to the epsilon-amino group of a specific lysine residue of lipoyl domains of lipoate-dependent enzymes By similarity. HAMAP MF_01602
Sequence similarities	Belongs to the lplA family.
