![]() Genomic technologies have provided the capacity to unlock the complex interactions between organisms and entire biological systems. They also have the ability to fix atmospheric nitrogen through the use of nitrogenase enzymes. They can also tolerate extremely adverse conditions, such as high salinity, low pH, and high and low light irradiance. Cyanobacteria can inhabit almost any environment, including arid and semi-arid environments and the Arctic and Antarctic.

PLoS ONE 17(10):Įditor: Arabinda Ghosh, Gauhati University, INDIA Through this computational analysis, we can gain a better understanding of the bias in codon usage by analyzing the amino acid composition of the Cyanobacterial proteome.Ĭitation: Mohanta TK, Mohanta YK, Avula SK, Nongbet A, Al-Harrasi A (2022) Virtual 2D map of cyanobacterial proteomes. The study can enable us to generate a high-resolution cell map to monitor proteomic dynamics. Several proteins within the Cyanobacterial proteome were found to encode Selenocysteine (Sec) amino acid, while Pyrrolysine amino acids were not detected. A virtual 2D map of Cyanobacterial proteome showed a bimodal distribution of molecular weight and pI. The proteins with higher pI are likely to contain repetitive amino acids. It was found that the Cyanobacterial proteome encodes a greater number of acidic- pI proteins, and their average pI is 6.437. The isoelectric point ( pI) of the Cyanobacterial proteome ranges from 2.13 to 13.32. A Cyanobacterial proteome encodes 312.018 amino acids per protein, with a molecular weight of 182173.1324 kDa per proteome. Therefore, we conducted a proteome-wide analysis of the Cyanobacteria proteome and found Calothrix desertica as the largest (680331.825 kDa) and Candidatus synechococcus spongiarum as the smallest (42726.77 kDa) proteome of the cyanobacterial kingdom. A detailed proteomics study of Cyanobacteria has not been conducted despite extensive study of their genome sequences. Cyanobacteria are prokaryotic Gram-negative organisms prevalent in nearly all habitats.
