crystal structure of the eucaryotic mono-adp-ribosyltransferase art2.2; crystal form c (p3121)
|SCOPe||1gy0 / SUPFAM|
- NAD+ + protein L-arginine nicotinamide + Nomega-(ADP-D-ribosyl)-protein-L-arginine NADP+ + protein L-arginine nicotinamide + Nomega-[(2'-phospho-ADP)-D-ribosyl]-protein-L-arginine
as well as the corresponding reaction using nicotinamide adenine dinucleotide phosphate
- NADP+ + protein L-arginine nicotinamide + Nomega-(ADP-D-ribosyl)-protein-L-arginine NADP+ + protein L-arginine nicotinamide + Nomega-[(2'-phospho-ADP)-D-ribosyl]-protein-L-arginine
Thus, the two substrates of this enzyme are NAD+ (or NADP+) and protein L-arginine, whereas its two products are nicotinamide and Nomega-(ADP-D-ribosyl)-protein-L-arginine (or Nomega-[(2'-phospho-ADP)-D-ribosyl]-protein-L-arginine, respectively).
This enzyme belongs to the family of glycosyltransferases, specifically the pentosyltransferases. The systematic name of this enzyme class is NAD(P)+:protein-L-arginine ADP-D-ribosyltransferase. Other names in common use include ADP-ribosyltransferase, mono(ADP-ribosyl)transferase, NAD+:L-arginine ADP-D-ribosyltransferase, NAD(P)+-arginine ADP-ribosyltransferase, and NAD(P)+:L-arginine ADP-D-ribosyltransferase.
At least five forms of the enzyme have been characterised to date, some of which are attached to the membrane via glycosylphosphatidylinositol (GPI) anchors, while others appear to be secreted. The enzymes contain ~250-300 residues, which encode putative signal sequences and carbohydrate attachment sites. In addition, the N- and C-termini are predominantly hydrophobic, a characteristic of GPI-anchored proteins.
