RT "Nicotinamidase participates in the salvage pathway of NAD biosynthesis in
RT Arabidopsis.";
RL Plant J. 49:1020-1029(2007).
CC -!- FUNCTION: Catalyzes the deamidation of nicotinamide, an early step in
CC the NAD(+) salvage pathway. Prevents the accumulation of intracellular
CC nicotinamide, a known inhibitor of poly(ADP-ribose) polymerases (PARP
CC enzymes). {ECO:0000269|PubMed:17335512}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + nicotinamide = NH4(+) + nicotinate;
CC Xref=Rhea:RHEA:14545, ChEBI:CHEBI:15377, ChEBI:CHEBI:17154,
CC ChEBI:CHEBI:28938, ChEBI:CHEBI:32544; EC=3.5.1.19;
CC Evidence={ECO:0000269|PubMed:17335512};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=118 uM for nicotinamide {ECO:0000269|PubMed:17335512};
CC Note=kcat is 0.93 sec(-1) with nicotinamide as substrate.
CC {ECO:0000269|PubMed:17335512};
CC pH dependence:
CC Optimum pH is 6.5-7.0. {ECO:0000269|PubMed:17335512};
CC -!- PATHWAY: Cofactor biosynthesis; nicotinate biosynthesis; nicotinate
CC from nicotinamide: step 1/1. {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q8S8F9-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q8S8F9-2; Sequence=VSP_057303, VSP_057304;
CC -!- TISSUE SPECIFICITY: Expressed in roots and stems, and at lower levels
CC in flowers, siliques and leaves. {ECO:0000269|PubMed:17335512}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC conditions, but mutant plants have decreased endogenous levels of NAD
CC and NADP and display abnormal hypersensitivity to exogenous treatment
CC with abscisic acid (ABA) and sodium chloride (NaCl).
CC {ECO:0000269|PubMed:17335512}.
CC -!- SIMILARITY: Belongs to the isochorismatase family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAD15566.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
