tRNA splicing in yeast and wheat germ. A cyclic phosphodiesterase implicated in the metabolism of ADP-ribose 1',2'-cyclic phosphate.

Adenosine diphosphate (ADP)-ribose 1",2"-cyclic phosphate (Appr > p) is produced as a result of transfer RNA (tRNA) splicing in the yeast Saccharomyces cerevisiae and probably in other eukaryotes. Endonucleolytic cleavage and ligation result in a mature length tRNA with a 2'-phosphate at the splice junction. This 2'-phosphate is transferred to NAD to produce Appr > p. Metabolism of Appr > p requires hydrolysis of the 1",2"-cyclic phosphate linkage. We show here that yeast has a unique cyclic phosphodiesterase that can hydrolyze Appr > p, ribose 1,2-cyclic phosphate, and ribose 1,3-cyclic phosphate to the corresponding ribose 1-phosphate derivatives. The cyclic phosphodiesterase is highly specific for Appr > p; there is 20-fold less activity on ribose 1,3-cyclic phosphate and no detectable activity on nucleoside 2',3'-cyclic phosphates. A similar cyclic phosphodiesterase is present in wheat germ. The wheat germ cyclic phosphodiesterase activity co-chromatographs with a 2',3'-cyclic nucleotide 3'-phosphodiesterase that was previously identified and purified. The purified wheat germ enzyme has a distinct preference for Appr > p and ribose cyclic phosphate compared to guanosine 2',3'-cyclic phosphate and shares other biochemical characteristics with the yeast enzyme. << Less

Characterization of the Saccharomyces cerevisiae cyclic nucleotide phosphodiesterase involved in the metabolism of ADP-ribose 1',2'-cyclic phosphate.

ADP-ribose 1",2"-cyclic phosphate (Appr>p) is produced in yeast and other eukaryotes as a consequence of tRNA splicing. This molecule is converted to ADP-ribose 1"-phosphate (Appr-1"p) by the action of the cyclic nucleotide phosphodiesterase (CPDase). Comparison of the previously cloned CPDase from Arabidopsis with proteins having related cyclic phosphodiesterase or RNA ligase activities revealed two histidine-containing tetrapeptides conserved in these enzyme families. Using the consensus phosphodiesterase signature, we have identified the yeast Saccharomyces cerevisiae open reading frame YGR247w as encoding CPDase. The bacterially expressed yeast protein, named Cpd1p, is able to hydrolyze Appr>p to Appr-1"p. Moreover, as with the previously characterized Arabidopsis and wheat CPDases, Cpd1p hydrolyzes nucleosides 2',3'-cyclic phosphates (N>p) to nucleosides 2'-phosphates. Apparent K (m)values for Appr>p, A>p, U>p, C>p and G>p are 0.37, 4.97, 8.91, 12.18 and 14.29 mM, respectively. Site-directed mutagenesis of individual amino acids within the two conserved tetrapeptides showed that H(40)and H(150)residues are essential for CPDase activity. Deletion analysis has indicated that the CPD1 gene is not important for cellular viability. Likewise, overexpression of Cpd1p had no effect on yeast growth. These results do not implicate an important role for Appr>p or Appr-1"p in yeast cells grown under standard laboratory conditions. << Less
