Proteomic analysis of mouse kidney peroxisomes: identification of RP2p as a peroxisomal nudix hydrolase with acyl-CoA diphosphatase activity.
Ofman R., Speijer D., Leen R., Wanders R.J.A.
Proteomic analysis of mouse kidney peroxisomes resulted in the identification of a novel nudix hydrolase designated RP2p, which is encoded by the D7RP2e gene. RP2p consists of 357 amino acids and contains two conserved domains: a nudix hydrolase domain and a CoA-binding domain. In addition, a PTS ... >> More
Proteomic analysis of mouse kidney peroxisomes resulted in the identification of a novel nudix hydrolase designated RP2p, which is encoded by the D7RP2e gene. RP2p consists of 357 amino acids and contains two conserved domains: a nudix hydrolase domain and a CoA-binding domain. In addition, a PTS (peroxisomal targeting signal) type 1 (Ala-His-Leu) was found at the C-terminus. Analysis of the enzyme characteristics revealed that RP2p is a CoA diphosphatase with activity towards CoA, oxidized CoA and a wide range of CoA esters, including choloyl-CoA and branched-chain fatty-acyl-CoA esters. The enzymatic properties of RP2p indicate that at low substrate concentrations medium and long-chain fatty-acyl-CoA esters are the primary substrates. Enzyme activity was optimal at pH 9 or above, and required the presence of Mg2+ or Mn2+ ions. Subcellular fractionation studies revealed that all CoA diphosphatase activity in mouse kidney is restricted to peroxisomes. << Less

The endoplasmic reticulum is a cellular hub of lipid metabolism, coordinating lipid synthesis with continuous changes in metabolic flux. Maintaining ER lipid homeostasis despite these fluctuations is crucial to cell function and viability. Here, we identify a novel mechanism that is crucial for normal ER lipid metabolism and protects the ER from dysfunction. We identify the molecular function of the evolutionarily conserved ER protein FIT2 as a fatty acyl-coenzyme A (CoA) diphosphatase that hydrolyzes fatty acyl-CoA to yield acyl 4'-phosphopantetheine. This activity of FIT2, which is predicted to be active in the ER lumen, is required in yeast and mammalian cells for maintaining ER structure, protecting against ER stress, and enabling normal lipid storage in lipid droplets. Our findings thus solve the long-standing mystery of the molecular function of FIT2 and highlight the maintenance of optimal fatty acyl-CoA levels as key to ER homeostasis. << Less

The nudix hydrolase 7 is an Acyl-CoA diphosphatase involved in regulating peroxisomal coenzyme A homeostasis.
Reilly S.J., Tillander V., Ofman R., Alexson S.E., Hunt M.C.
Coenzyme A (CoASH) is an obligate cofactor for lipids undergoing beta-oxidation in peroxisomes. Although the peroxisomal membrane appears to be impermeable to CoASH, peroxisomes contain their own pool of CoASH. It is believed that CoASH enters peroxisomes as acyl-CoAs, but it is not known how this ... >> More
Coenzyme A (CoASH) is an obligate cofactor for lipids undergoing beta-oxidation in peroxisomes. Although the peroxisomal membrane appears to be impermeable to CoASH, peroxisomes contain their own pool of CoASH. It is believed that CoASH enters peroxisomes as acyl-CoAs, but it is not known how this pool is regulated. The mouse nudix hydrolase 7 (NUDT7alpha) was previously identified in peroxisomes as a CoA-diphosphatase, and therefore suggested to be involved in regulation of peroxisomal CoASH levels. Here we show that mouse NUDT7alpha mainly acts as an acyl-CoA diphosphatase, with highest activity towards medium-chain acyl-CoAs, and much lower activity with CoASH. Nudt7alpha mRNA is highly expressed in liver, brown adipose tissue and heart, similar to enzymes involved in peroxisomal lipid degradation. Nudt7alpha mRNA is down-regulated by Wy-14,643, a peroxisome proliferator-activated receptor alpha (PPARalpha) ligand, in a PPARalpha-dependent manner in mouse liver. In highly purified peroxisomes, nudix hydrolase activity is highest with C(6)-CoA and is decreased by fibrate treatment. Under certain conditions, such as treatment with peroxisome proliferators or fasting, an increase in peroxisomal CoASH levels has been reported, which is in line with a decreased expression/activity of NUDT7alpha. Taken together these data suggest that NUDT7alpha function is tightly linked to peroxisomal CoASH/acyl-CoA homeostasis. << Less
