The analysis of protein sequences provides the information about the preference of amino acid residues and their distribution along the sequences for understanding the secondary and tertiary structures of proteins and their functions. The identification of similar motifs in protein sequences would help to predict the structurally or functionally important regions.
Background hidden markov models (hmm) are a powerful tool for analyzing biological sequences in a wide variety of applications, from profiling functional protein families to identifying functional domains. The standard method used for hmm training is either by maximum likelihood using counting when sequences are labelled or by expectation maximization, such as the baum–welch algorithm, when.
Genomics and bioinformatics play an increasingly important and transformative role in medicine, society and agriculture. The mapping of the human genome has revealed 35,000 or so genes which might code for more than one protein, resulting in 100,000 proteins for the humans alone. Since proteins are attractive targets for developing drugs, efforts are now underway to map sequences and assign functions to many novel proteins.

The prediction is performed in two steps: (i) the input sequences are converted into a set of numerical features that describe certain, relevant characteristics of the protein chain; and (ii) the feature values are fed into four predictive models that output the predicted propensity for material production, purification, crystallization and diffraction quality crystallization, respectively; we use a support vector machine (svm), which was previously shown to provide high-quality predictions.

Sequence homology is the biological homology between dna, rna, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of dna can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene transfer event (xenologs).
