Proteins are one of the important fundamental units of all living cells. Proteins have a wide range of functions within all the living beings. Some of the important functions such as DNA replication, catalysis of metabolic reactions, transportation of molecules from one location to another etc. The building blocks of proteins are amino acids. Amino acids are made from an amine -NH2 and a carboxylic acid -COOH functional groups as well as a side chain which is specific to each amino acid. There are almost 20 amino acids found in human body that usually varies in their R groups. In proteins, the amino acids are linked to each other by means of peptide bonds.

Protein sequences can be analysed by several tools, based on the ProtParam tools on the Expasy Proteomics Server. The module is part of the SeqUtils package. The ProteinAnalysis class takes one argument, the protein sequence as a string and builds a sequence object using the Bio. Seq module. This is done just to make sure the sequence is a protein sequence and not anything else. You can set several parameters that control the computation of a scale profile, such as the window size and the window edge relative weight value.

Biosignal Processing and Analysis This lab focuses on using, analysing and processing EEG data and provides a platform for EEG data analysis and visualization, to understand the correlations of neural activity through electroencephalography data. The lab is an education platform for engineers and biologists without major requirements for learning methods in signal processing. Filtering and removal of artifacts in Biosignals Point processes and models Analysis of Biosignals activity and artifacts Power spectrum calculations using different windows Study the changes in the PSDs by varying window width Temporal structure in EEG Motor unit firing pattern Modeling network activity as in biological circuits Modeling synaptic network connectivity Reconstructing Averaged Population Response Biosignal Import and Channel Analysis Time-frequency analysis of Biosignals Bioinformatics and Data Science in Biotechnology This lab is a connection of bioinformatics experiments performed using R programming. Educating this will allow users to learn how to use R as an open source language for learning bioinformatics data processing. Specifically, this lab will help analyse biological sequence data using simple R code snippets. Primarily, it is connected with neurobiology, psychology, neurology, clinical neurophysiology, electrophysiology, biophysical neurophysiology, ethology, neuroanatomy, cognitive science and other brain sciences. Various experiments will deal with the several parameters of Hodgkin-Huxley equations and will model resting and action potentials, voltage and current clamp, pharmacological effects of drugs that block specific channels etc.

The comparative study of the physicochemical properties is important to know role of a protein in exploring its molecular evolution. A number of online and offline tools are available for calculating the physico-chemical properties of a single protein sequence. Furthermore, it provides a graphical representation of protein physico-chemical properties for analysis and visualization of data in a user-friendly manner.

Anal Biochem. Computed parameters include molecular weight, theoretical pI, amino acid composition, atomic composition, extinction coefficient, estimated half-life, instability index, aliphatic index and grand average of hydropathicity. This is an example of comparative analysis of multiple sequences. Seq module. By default, the amino acids at the remaining window positions have the same weight, but you can make the residue at the center of the window have a larger weight than the others by setting the edge value for the residues at the beginning and end of the interval to a value between 0 and 1. Moreover, current methods do not analyze multiple sequences for comparative analysis. The pKa value of Amino acids depends on its side chain. Login Register.

Molecular Weight In protParam, the molecular weight of protein is calculated by the addition of average isotopic masses of amino acids in the provided protein and the average isotopic mass of one water molecule.

ProtParam computes various physico-chemical properties that can be deduced from a protein sequence.

It has an important role in defining the pH dependent characteristics of a protein. This provides insight for functional analysis and molecular evolution. The interface also provides values for molecular weight, extinction coefficient, instability index, aliphatic index and grand average of hydropathycity GRAVY [ 9 ] for the protein sequences Table 2 in a comparative manner among 17 mammalian species. Proteins differ from one another in their structure, primarily in their sequence of amino acids. The site is secure. Contact Us. Extinction coefficient The extinction coefficient illustrates how much light a protein absorbs at a certain wavelength. Keywords: Calculate phycicochemical parameter, protein, Swiss-Prot, TrEMBL, protein sequence, molecular weight, theortical pl, amino acid composition, atomic composition, extinction coefficient, bio.
