Collagen is the fundamental structural protein, comprising 25 35% of the total body protein, its rod-like triple helix providing support in many tissues.
This excitement was partly due to the discovery of the α-helical fold by Linus Pauling and his group as a fundamental structural principle embodied in the muscle proteins myosin and tropomyosin; and in the years that followed, more α-helix-rich proteins were discovered and grouped together as fibrous proteins.
The transmembrane (TM) helix is the fundamental structural unit of helix-bundle membrane proteins.
Many of the oscillating genes are key tissue-specific transcription factors, characteristic structural proteins or are involved in metabolic pathways fundamental for that particular tissue [ 7– 10].
Tubulins are a family of eukaryotic structural proteins that comprise microtubules, fundamental components of the spindle in cell division, the axoneme in cilia and flagella, mediators of cell shape, and dynein/kinesin-based cell trafficking [ 13- 15].
Therefore, the main aim of this work is to understand the effects of cytosine modification on the fundamental structural properties of DNA before binding to proteins or other ligands.
One of the most fundamental structural characteristics of genomes is the order in which protein-coding genes are arranged on chromosomes.
This is important when considering molecular evolution within a system: when deeper phylogenies are considered, the likelihood of fundamental structural differences in the system between species increases, due to gain or loss of genes or protein-protein interactions, impacting one's ability to investigate system-level, evolutionary constraints acting on a molecule.
Chirality, lack of mirror symmetry, is an important and fundamental structural property of matter, and can be extensively found in various biological molecules, such as proteins, nucleic acids, and saccharides.
This information determines the sequence of amino acid building blocks of protein molecules, which include, among others, structural proteins such as collagen, respiratory proteins such as hemoglobin, and numerous enzymes responsible for the organism's fundamental life processes.
