Protein

NAD-dependent protein deacylase SIR2rp3

Gene

SIR2rp3

Organism
Leishmania major
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

NAD-dependent lysine demalonylase, desuccinylase and deglutarylase that specifically removes malonyl, succinyl and glutaryl groups on target proteins. Has weak NAD-dependent protein deacetylase activity; however this activity may not be physiologically relevant in vivo.UniRule annotation

Miscellaneous

This protein may be expected to contain an N-terminal transit peptide but none has been predicted.UniRule annotation

Catalytic activityi

NAD+ + a malonylprotein = nicotinamide + O-malonyl-ADP-ribose + a protein.UniRule annotation
NAD+ + a succinylprotein = nicotinamide + O-succinyl-ADP-ribose + a protein.UniRule annotation
NAD+ + a glutarylprotein = nicotinamide + O-glutaryl-ADP-ribose + a protein.UniRule annotation

Domaini

In contrast to class I sirtuins, class III sirtuins have only weak deacetylase activity. Difference in substrate specificity is probably due to a larger hydrophobic pocket with 2 residues (Tyr-56 and Arg-59) that bind to malonylated and succinylated substrates and define the specificity.UniRule annotation

Sequence similaritiesi

Belongs to the sirtuin family. Class III subfamily.UniRule annotation
