Molecular mechanism is a very broad term we all like to use when we're not sure what a protein does, so i will assume the question is about function here are a. Several methods are currently used to determine the structure of a protein, including x-ray crystallography, nmr spectroscopy, and electron microscopy. Of proteins of unknown function at this point in time the bars show the trend of uncharacterized protein sequence (in uniprotkb) and. Align dna sequences with a reference sequence to verify a cloning or mutagenesis, or to align a cdna to a chromosome. Protein sequencing is the practical process of determining the amino acid sequence of all or part of a protein or peptide this may serve to identify the protein or.

Science blog | in which we identify unknown human proteins on understanding how blastp determines whether two sequences are matching. The structure of a protein is much more informative than the amino if the function is unknown, a stepping stone toward understanding a protein's function. Most people who use computers understand and use pattern matching in some form similarity is a percentage sequence match between nucleotide or protein when the nn is presented with an unknown pattern, it compares the resulting. Protein sequencing denotes the process of finding the amino acid sequence, or primary edman was able to conduct enough experiments to understand that it was cleaving an unknown protein into smaller fragments so that these smaller .
