If we alter even one amino acid in the chain it results in a non-functioning protein or what we call a gene mutation. The formation and ordering of these amino acids in proteins are extremely specific. It is this R group that lends a particular protein its unique structure.Įvery protein is determined by the sequencing of the amino acids. But each has a different variable group known as the “R” group. All of these have a carboxyl group and an amino group. There are in all twenty amino acids in the human body. Protein gets all its properties from its primary structure. The primary structure is the unique formation and order in which the amino acids (the building blocks) combine and link to give us a protein molecule.

Let us now look at the four types of protein structure that make up a protein molecule. One of the smallest protein molecules is insulin, and the largest being Titin which consist of 34,350 amino acids.
It actually depends on the number of polypeptide molecules it contains. Now one or more of these polypeptide chains twist or fold spontaneously and a protein is formed. These amino acids are connected together with peptide bonds, and a few such bonds linking together form a polypeptide chain. What this actually entails is that proteins are long chain-like structure, with amino acids being the main ingredient. Now we previously learnt that amino acids are the building blocks of proteins. Platform that integrates several algorithms for signal peptide identification, transmembrane helix prediction, transmembrane β-strand prediction, secondary structure prediction and homology modeling.Proteins are what we call biological polymers (i.e. The required input is the DNA and not the protein sequence, as such the software can automatically design the oligonucleotides needed for PCR amplification of the constructs. ProteinCCD functions as a meta-server, concerning secondary structure, disorder, coiled coils, transmembrane segments, domains and domain linkers. The server focused on visual approach for protein comparison of different protein features above the sequence level.Ĭrystallographic Construct Design.
Integration of several algorithms for domains, disorder, transmembrane prediction and multiple sequence alignment. Platform that integrates variety of tools for protein sequence analysis and the prediction of protein structure and function.
