Engineering of the fluorescent-energy-conversion arm of phi29 DNA packaging motor for single-molecule studies.

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
The bacteriophage phi29 DNA packaging motor contains a protein core with a central channel comprising twelve copies of re-engineered gp10 protein geared by six copies of packaging RNA (pRNA) and a DNA packaging protein gp16 with unknown copies. Incorporation of this nanomotor into a nanodevice would be beneficial for many applications. To this end, extension and modification of the motor components are necessary for the linkage of this motor to other nanomachines. Here the re-engineering of the motor DNA packaging protein gp16 by extending its length and doubling its size using a fusion protein technique is reported. The modified motor integrated with the eGFP-gp16 maintains the ability to convert the chemical energy from adenosine triphosphate (ATP) hydrolysis to mechanical motion and package DNA. The resulting DNA-filled capsid is subsequently converted into an infectious virion. The extended part of the gp16 arm is a fluorescent protein eGFP, which serves as a marker for tracking the motor in single-molecule studies. The activity of the re-engineered motor with eGFP-gp16 is also observed directly with a bright-field microscope via its ability to transport a 2-microm-sized cargo bound to the DNA.
