MassSearch: Searching SwissProt or EMBL by protein mass after digestion

 

 

Filling and submitting the following form (see also the example) will search SwissProt or the selected database for sequences which when digested by the given enzyme will match the given set of masses.

An optional modifier aa=mass indicates that the weight of the amino acid aa is to be considered mass. For the cases of digestion with CNBr or TrypsinCysModified, (cysteine is transformed into homoserine or homoserinelactone for CNBr and to aminoethylcysteine for the second) the modifications are done automatically.
( for further information). 


 
The result should be mailed to:
(Email address)
Title of your job (optional):

You can chose between monoisotopic and average masses

You may enter the masses as MH+ (finally :-)
