Editor to share with you how to use biopython to calculate the isoelectric point of protein. I hope you will get something after reading this article. Let's discuss it together.

Calculation of Isoelectric Point of protein by biopython

Recently, some proteome projects are being done, in which the isoelectric point of the protein needs to be calculated. There are many websites on the Internet that can provide corresponding computing services, but all of them are calculated for a single protein sequence, and I need to calculate the isoelectric point of all protein sequences in the proteome. Several functions in Bioython are used for calculation, and the code is as follows:

Fasta file of from Bio.SeqUtils.ProtParam import ProteinAnalysisfrom Bio import SeqIO# designated protein sequence protein_file = "protein.fasta" # traversing each protein sequence Calculate isoelectric point for seq_record in SeqIO.parse (protein_file, "fasta"): P = ProteinAnalysis (str (seq_record.seq)) # the calculation function of isoelectric point is: isoelectric_point print (seq_record.id +'\ t'+ str (p.isoelectric_point () after reading this article, I believe you have some understanding of "how to use biopython to calculate the isoelectric point of protein", if you want to know more about it Welcome to follow the industry information channel, thank you for reading!
