Introduction • Basic bioinformatics Databases • NCBI home page • Query and return results • DNA sequence results page • Protein sequence results page
Bioinformatics Database • Bioinformatic Databases contain information forvarious biological data: • Consider the following [NCBI] query: • What is the DNA and amino acid sequence for the following protein: • homo sapiens[organism] AND elastase[title] AND leukocyte[title]
B.P. and AA sequence Note p08246 [protein code] and Base 1287 [highlighted in blue] is start codon ATG
Graphic file for protein (p08246) CDD: conserved domains; disulphide bonds between to cystine AA is important in the protein folding process: 1’ to 2’ to 3 ‘
Main bioinformatics databases • DNA (nucleic acid) sequences: • NCBI(usa){ leukocyte elastase gene}, Graph format • EMBl (europe) { leukocyte elastase gene}, • Genome Databases: Ensemble elastase record • UniProt protein sequences: Elastase record • More information in the January issue of • Nucleic Acid Research (open access)
