Utilization of Exogenous and Endogenous Ornithine by <i>Neurospora crassa</i> is a research paper published in Journal of Bacteriology (1968). On theSindex it has a DataRank of 2.6. It has been cited 44 times, with 31 citing works in its 1-hop citation network. Its calibrated FAIR score is 49/100.
Through the use of a mutant deficient in ornithine-δ-transaminase (OTA), it is shown that this enzyme normally has no obligate or even major biosynthetic role in Neurospora . The pathways of ornithine and proline synthesis proceed wholly independently of each other in OTA-less strains. It is probable that OTA functions as an enzyme of arginine catabolism. With mutants affected in OTA, ornithine transcarbamylase, and the synthesis of ornithine, it was demonstrated that exogenous and endogenous ornithine are utilized in different ways. Exogenous ornithine is destined mainly for catabolism, whereas endogenous ornithine is destined mainly for biosynthesis. It is suggested that this distinction depends upon differences in the intracellular location or origin of the two sources of ornithine.

Citation Network Contribution
2.0
From 28 citing papers with measurable signal
Ranked by citation count — the same ordering the engine uses when summing log1p(Cq) over citers.
DataRank blends this paper's own citation count with the influence of the papers that cite it. Here, roughly 22% comes from its base citations and 78% from the citation network (28 citing papers contributed measurable signal).
Citers are pulled from OpenAlex sorted by cited_by_count:descand capped per paper, so when the cap binds we keep the highest-signal references and the score is reproducible across reruns.
