Nitrite transport activity of the ABC-type cyanate transporter of the cyanobacterium Synechococcus elongatus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In addition to the ATP-binding cassette (ABC)-type nitrate/nitrite-bispecific transporter, which has a high affinity for both substrates (K(m), approximately 1 microM), Synechococcus elongatus has an active nitrite transport system with an apparent K(m) (NO(2)(-)) value of 20 microM. We found that this activity depends on the cynABD genes, which encode a putative cyanate (NCO(-)) ABC-type transporter. Accordingly, nitrite transport by CynABD was competitively inhibited by NCO(-) with a K(i) value of 0.025 microM. The transporter was induced under conditions of nitrogen deficiency, and the induced cells showed a V(max) value of 11 to 13 micromol/mg of chlorophyll per h for cyanate or nitrite, which could supply approximately 30% of the amount of nitrogen required for optimum growth. Its relative specificity for the substrates and regulation at transcriptional and posttranslational levels suggested that the physiological role of the bispecific cyanate/nitrite transporter in S. elongatus is to allow nitrogen-deficient cells to assimilate low concentrations of cyanate in the medium. Its contribution to nitrite assimilation was significant in a mutant lacking the ABC-type nitrate/nitrite transporter, suggesting a possible role for CynABD in nitrite assimilation by cyanobacterial species that lack another high-affinity mechanism(s) for nitrite transport.
