patmatmotifs reads a protein sequence and searches it against the PROSITE database of motifs. It writes a standard EMBOSS report file with details of the location and score of any matching motifs. Optionally, full documentation for matching patterns is given in the report. Optionally, simple post-translational modification sites are not reported. PROSITE must be processed by running prosextract before running patmatmotifs.
The home web page of PROSITE is: http://www.expasy.ch/prosite/. Quoting from the PROSITE user's documentation:"PROSITE is a method of determining what is the function of uncharacterized proteins translated from genomic or cDNA sequences. It consists of a database of biologically significant sites and patterns formulated in such a way that with appropriate computational tools it can rapidly and reliably identify to which known family of protein (if any) the new sequence belongs.
In some cases the sequence of an unknown protein is too distantly related to any protein of known structure to detect its resemblance by overall sequence alignment, but it can be identified by the occurrence in its sequence of a particular cluster of residue types which is variously known as a pattern, motif, signature, or fingerprint. These motifs arise because of particular requirements on the structure of specific region(s) of a protein which may be important, for example, for their binding properties or for their enzymatic activity. These requirements impose very tight constraints on the evolution of those limited (in size) but important portion(s) of a protein sequence. To paraphrase Orwell, in Animal Farm, we can say that "some regions of a protein sequence are more equal than others" !
The use of protein sequence patterns (or motifs) to determine the function(s) of proteins is becoming very rapidly one of the essential tools of sequence analysis. This reality has been recognized by many authors, as it can be illustrated from the following citations from two of the most well known experts of protein sequence analysis, R.F. Doolittle and A.M. Lesk:
"There are many short sequences that are often (but not always) diagnostics of certain binding properties or active sites. These can be set into a small subcollection and searched against your sequence (1)".
"In some cases, the structure and function of an unknown protein which is too distantly related to any protein of known structure to detect its affinity by overall sequence alignment may be identified by its possession of a particular cluster of residues types classified as a motifs. The motifs, or templates, or fingerprints, arise because of particular requirements of binding sites that impose very tight constraint on the evolution of portions of a protein sequence (2)."
It is common to find that a search of the PROSITE database against a protein sequence will report many matches to the short motifs that are indicative of the post-translational modification sites, such as glycolsylation, myristylation and phosphorylation sites. These reports are often unwanted and are not normally reported. You can turn reporting of these short motifs on by giving the -noprune option on the command-line.

Vision is effected through the absorption of a photon by cis- # retinal which is isomerized to trans-retinal. This isomerization leads to a # change of conformation of the protein. Opsins are integral membrane proteins # with seven transmembrane regions that belong to family 1 of G-protein coupled # receptors (see <PDOC00210>). # # In vertebrates four different pigments are generally found. Rod cells, which # mediate vision in dim light, contain the pigment rhodopsin. Cone cells, which # function in bright light, are responsible for color vision and contain three # or more color pigments (for example, in mammals: red, blue and green). # # In Drosophila, the eye is composed of 800 facets or ommatidia. Each # ommatidium contains eight photoreceptor cells (R1-R8): the R1 to R6 cells are # outer cells, R7 and R8 inner cells. Each of the three types of cells (R1-R6, # R7 and R8) expresses a specific opsin. # # Proteins evolutionary related to opsins include squid retinochrome, also known # as retinal photoisomerase, which converts various isomers of retinal into 11- # cis retinal and mammalian retinal pigment epithelium (RPE) RGR , a protein # that may also act in retinal isomerization. # # The attachment site for retinal in the above proteins is a conserved lysine # residue in the middle of the seventh transmembrane helix.
