Results: A neural network ensemble (NNE) method that utilizes negative correlation learning (NCL) approach was developed for identification of structurally conserved residues (SCRs) in proteins using features that represent amino acid conservation and composition, physico-chemical properties and structural properties.
While investigating a set of spectra, the research of isosbestic point, direct or hidden, is very important in order to check an eventual conservation of composition, either quantitative or qualitative.
Synteny conservation, nucleotide composition, and phylogenetic analyses of the cluster genes indicate that the B. cinerea cluster was acquired via horizontal transfer from a Fusarium donor.
Here, we implemented a NNE method that utilizes NCL approach for prediction of SCRs using features that represent the amino acid conservation and composition, physico-chemical properties and structural properties, such as solvent accessibility, secondary structures, hydrogen bonding and residue compactness.
This conservative shuffling procedure generates random alignments, preserving length, base composition, overall conservation, local conservation, and gap pattern.
Based on the extensive distribution, as well as the conservation of structure, composition, and functions of LDs from almost all living organisms, we propose a hypothesis that the LD is a conserved organelle from bacteria to humans (Fig. 1).
Here, we exploited the extensive evolutionary conservation of mitochondrial composition and function between mammalian and C. elegans mitochondria to identify a biologically-relevant cadre of complex I subunits to investigate in human patients with impaired complex I respiratory capacity.
Altogether, our study illustrates a conservation of DGC composition and interactions between Drosophila and vertebrates at the synapse, highlights new proteins associated with this complex and suggests an unsuspected trans-synaptic function of Dg.
The data presented in Fig. 2A not only illustrate the greater conservation of nucleotide composition at the second codon position, but they also show that mitochondrial genomes have a lowered GC content at the second position, even for those species where the GC content at the other two codon positions is greater than 50%.
Three types of sequence information are used: composition, conservation, and overrepresentation.
