|October 1, 2015
Summary
Bioinformatic analysis reveals distinct protein phosphatase sets in plants versus humans. Significant variations also exist among different plant species, including mosses and flowering plants.
Area of Science:
- Biochemistry
- Bioinformatics
- Plant Biology
Background:
- Protein phosphatases are crucial enzymes regulating cellular processes in all eukaryotes.
- Comparative analysis of phosphatomes provides insights into evolutionary relationships and functional diversification.
Purpose of the Study:
- To compare the protein phosphatases of higher plants with the human phosphatom.
- To identify and characterize plant homologues of known catalytic domains.
- To investigate evolutionary differences in protein phosphatase sets between plants and mammals, and among plant species.
Main Methods:
- Bioinformatic sequence and profile comparison.
- Identification of catalytic domains.
- Clustering analysis of plant and mammalian protein phosphatases.
Main Results:
- 204 plant homologues from Physcomitrella patens and Arabidopsis thaliana were identified.
- Fundamental differences were observed between plant and human phosphatomes.
- Significant variations in protein phosphatase sets were found among P. patens, A. thaliana, Oryza sativa, and Zea mays.
Conclusions:
- Plant and human protein phosphatases exhibit significant evolutionary divergence.
- Distinct protein phosphatase repertoires exist across different plant lineages, highlighting species-specific adaptations.

15.6K
Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.

02:54Evolutionary Relationships through Genome Comparisons
7.2K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

02:16Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes
17.4K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

01:59The Phragmoplast
6.6K
Cell division is essential for organismal growth and development. In animal cells, the central spindle and its associated proteins form the midbody, a structure that has an essential role in cytokinesis. In plants, the central spindle, along with the microtubules, actin, and other cell components, matures into the phragmoplast, which is necessary for cytokinesis. Unlike the stationary midbody, the phragmoplast expands centrifugally, eventually leading to the formation of the new cell wall.
