Mr038 (P05511) Protein Card

General Information

Name	Mr038
Alternative name(s)	Mr038
Organism	Conus marmoreus
Organism region	Indo-Pacific
Organism diet	molluscivorous
Protein Type	Wild type
Protein precursor	Mr038 precursor (5510)
Notes	The peptide mass was found by MS but it was not sequenced by MS/MS (Dutertre 2013). There is an ambiguity regarding which tryptophan residue is modified into a bromo-tryptophan residue.
