Abstract

Arginine decarboxylase (ADC) and agmatinase are part of an operon in Escherichia coli, which constitutes the primary pathway of polyamine synthesis from arginine. This pathway is also known to exist in plants, but until recently, neither agmatine nor ADC, the enzyme that synthesizes it, nor agmatinase the enzyme that is responsible for conversion of agmatine to putrescine, were known to exist in man or other mammals. We describe here the cloning of the agmatinase gene and the tissue distribution of its transcription product. Human agmatinase contains 352 amino acid residues and has a calculated molecular weight of 37,688 kDa. It has 56% similarity to E. coli agmatinase and 42% similarity to human arginases I and II and shares highly conserved substrate-binding domains with these well-characterized enzymes.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • eRegulons depend on nutritional status (AGMAT, MLXIPL), hormone levels (NR1I2, NR1I3, RXRA), and circadian rhythm (CLOCK).

    “This enabled us to identify eRegulons that depend on nutritional status, such as AGMAT30 and MLXIPL31; on hormone levels, such as NR1I2, NR1I3 and RXRA32; and on circadian rhythm, such as CLOCK33.”
  • Regulons that depend on nutritional status include Agmat and Mlxipl; on hormone levels include Nr1i2, Nr1i3 and Rxra; and on circadian rhythm include Clock.

    “This allowed us to identify regulons that depend on nutritional status, such as Agmat52 and Mlxipl53; on hormone levels, such as Nr1i2, Nr1i3 and Rxra54; and on circadian rhythm, such as Clock55.”

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.
