Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and serves as a visual framework for hanging details of the entire atomic structure ...
The description of a protein three dimensional structure as a network of hydrogen bonding interactions (HB plot) [12] was introduced as a tool for exploring protein structure and function. By analyzing the network of tertiary interactions, the possible spread of information within a protein can be investigated.
Computational system for predicting protein subchloroplast locations from its primary sequence. It can locate the protein whose subcellular location is chloroplast in one of the four parts: envelope (which consists of outer membrane and inner membrane), thylakoid lumen, stroma and thylakoid membrane. (bio.tools entry) [97]
They consist of a long polypeptide chain that usually adopts a single stable three-dimensional structure. They fulfill a wide variety of functions including providing structural stability to cells, catalyze chemical reactions that produce or store energy or synthesize other biomolecules including nucleic acids and proteins, transport essential ...
A consensus logo is a simplified variation of a sequence logo that can be embedded in text format. Like a sequence logo, a consensus logo is created from a collection of aligned protein or DNA/RNA sequences and conveys information about the conservation of each position of a sequence motif or sequence alignment [1] [4].
Align DNA, RNA, protein, or DNA + protein sequences via a variety of pairwise and multiple sequence alignment algorithms, generate phylogenetic trees to predict evolutionary relationships, explore sequence tracks to view GC content, gap fraction, sequence logos, translation ABI, DNA Multi-Seq, FASTA, GCG Pileup, GenBank, Phred
In biology literature, the term topology is also used to refer to mutual orientation of regular secondary structures, such as alpha-helices and beta strands in protein structure [3]. For example, two adjacent interacting alpha-helices or beta-strands can go in the same or in opposite directions.
C-alpha baton mode - trace the main chain of a protein by placing correctly spaced alpha-carbon atoms. Ca Zone -> Mainchain - convert an initial trace of the alpha-carbon atoms to a full main-chain trace. Place helix here - fit a sequence of amino acids in alpha helix conformation into density.
