Sentence examples for fixation machinery from inspiring English sources
Carbon fixation machinery requires proper assembly and functioning of carboxysome [ 1].
In both, components of the nitrogenase dependent cyanobacterial nitrogen fixation machinery are encoded, including structural genes of the nitrogenase nifH, nifD and nifK, cofactors (nifB, nifN, nifE, nifV, nifW) and processing proteins for metal centre biosynthesis (nifU, nifS).
A reduction in the CO2 fixation machinery, including proteins involved in the Carbon Concentrating Mechanism (CCM) (CcmM, Npun_R3840; 0.48-0.09-fold) and all the enzymes in the Calvin-Benson-Bassham Cycle (0.26-0.02-fold; Additional file 1) was clearly evident in the heterocysts.
In the + N case, functional categories linked to carbon fixation, photosynthesis, protein machinery, and cellular growth were highly enriched compared to the –N condition; reflecting the higher growth rate, higher cell mass, and increased chlorophyll content observed in + N.
However, the reviewer has left out an important point in the argument: Selection on the editing machinery to establish fixation in the first instance.
The 'editing machinery' was probably a means of fixation of selectively constrained pyrimidines under these reduced selection periods.
To overcome this, Cyanothece have developed mechanisms to switch/alternate the cellular and molecular machinery twice daily to temporally separate N2-fixation in the dark from photosynthesis in the light [ 6, 7].
Second, fixation bias inside MRI regions might be due to some non-symmetry in cellular molecular machinery involving DNA repair, replication, and/or recombination processes.
Pleiotropic costs can act against the fixation of defense strategies [ 52, 53] and there may be varying degrees of pleiotropy constraining the piRNA machinery across the Drosophila genus.
It is conceivable that these transcription factor genes respond to changes in the function of the photosynthetic machinery and related changes in chloroplast redox conditions and/or the production of different metabolites derived from CO2 fixation [ 4].
