Abstract

The primary structure of rat liver xanthine dehydrogenase (EC 1.1.1.204) was determined by sequence analysis of cDNA and purified enzyme. The enzyme consists of 1,319 amino acid residues with a calculated molecular mass of 145,034 Da, including initiation methionine, and is homologous to the previously reported Drosophila melanogaster enzyme (Lee, C. S., Curtis, D., McCarron, M., Love, C., Gray, M., Bender, W., and Chovnick, A. (1987) Genetics 116, 55-66; Keith, T. P., Riley, M. A., Kreitman, M., Lewontin, R. C., Curtis, D., and Chambers, G. (1987) Genetics 116, 67-73) with an identity of 52%. The enzyme exists originally as the NAD-dependent type in a freshly prepared sample. When the purified NAD-dependent type enzyme was digested with trypsin, it cleaved into three fragments with molecular masses of 20, 40, and 85 kDa and was irreversibly converted to the O2-dependent type. Comparison of the amino-terminal sequences of the three peptide fragments with the cDNA-deduced sequence reveals that the 20-, 40-, and 85-kDa peptide fragments correspond residues to 1-184, 185-539, and 540-1319 of the enzyme, respectively. Comparison of the 5'-p-fluorosulfonylbenzoyladenosine-labeled peptide sequence of the chicken enzyme (Nishino, T., and Nishino, T. (1989) J. Biol. Chem. 264, 5468-5473) reveals that the NAD binding site is associated with the 40-kDa fragment portion of the enzyme. Hydropathy analysis around the cysteine residues suggests that the 2Fe/2S sites are associated with the 20-kDa fragment portion of the enzyme.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
