## Mappings from an ID to a PFAM Accession number

### Description

This is an R object that contains mapppings from an ID to its PFAM Accession number (AC)

### Details

For each of the aliases listed above, there is a mapping object that corresponds which will map you from the ID type in the environments name to the appropriate PFAM accession number. So for example PFAMCAZY2AC will map from CAZY IDs to PFAM IDs while PFAMDE2AC will map from Descriptions to PFAM IDs.

Details on supported things that are mapped to:

CAZY: The CAZy database (<URL: http://afmb.cnrs-mrs.fr/CAZY/>) describes the families of structurally-related catalytic and carbohydrate-binding modules (or functional domains) of enzymes that degrade, modify, or create glycosidic bonds.

DE: Definition for all the Accession number in the database.

ID: Associated Identification for all the Accession number in the database.

HOMSTRAD: HOMSTRAD (HOMologous STRucture Alignment Database, <URL: http://www-cryst.bioc.cam.ac.uk/homstrad/>) is a curated database of structure-based alignments for homologous protein families.

INTERPRO: Associated INTERPRO ID for all the Accession number in the database. <URL: http://www.ebi.ac.uk/interpro/>

LOAD: LOAD ID for all the Accession number in the database.

MEROPS: The MEROPS database (<URL: http://merops.sanger.ac.uk/>) is an information resource for peptidases (also termed proteases, proteinases and proteolytic enzymes) and the proteins that inhibit them.

MIM: MIM (a.k.a. OMIM, <URL: http://www.ncbi.nlm.nih.gov/omim/>) is a catalog of human genes and genetic disorders authored and edited by Dr. Victor A. McKusick and his colleagues at Johns Hopkins and elsewhere. Reference: <MIM> MIM: McKusick, V.A.: Mendelian Inheritance in Man. A Catalog of Human Genes and Genetic Disorders.

PFAMB: Pfam-B is an automatic clustering of the rest of SWISSPROT and TrEMBL derived from the PRODOM database.

PRINTS: PRINTS (<URL: http://umber.sbs.man.ac.uk/dbbrowser/PRINTS/>) is a compendium of protein fingerprints.

PROSITEPROFILE: A list of associated PROSITE PROFILE ID.

RM: Reference Medline (<URL: http://www.ncbi.nlm.nih.gov/PubMed/>)

SMART: SMART (a Simple Modular Architecture Research Tool, <URL: http://smart.embl-heidelberg.de/>) allows the identification and annotation of genetically mobile domains and the analysis of domain architectures.

TC: Trusted cutoff for all the Accession number in the database.

TP: A list of associated Type field for the given Accession.

URL: A list of associated URL for all the Accession number in the database.

### Examples

            #To map from CAZY to PFAM IDs:
            x <- PFAMCAZY2AC
            # Get the CAZY identifiers that are mapped to a PFAM ID
            mapped_keys <- mappedkeys(x)
            # Convert to a list
            xx <- as.list(x[mapped_keys])
            if(length(xx) > 0) {
              # Get the PFAM ID for the first five CAZYs
              xx[1:5]
              # Get the first one
              xx[[1]]
            }

            #Or to use the DE2AC mapping:
            x <- PFAMDE2AC
            # Get the Descriptions that are mapped to a PFAM ID
            mapped_keys <- mappedkeys(x)
            # Convert to a list
            xx <- as.list(x[mapped_keys])
            if(length(xx) > 0) {
              # Get the PFAM ID for the first five DEs
              xx[1:5]
              # Get the first one
              xx[[1]]
            }

            #etc.
