Cal5b (P04260) Protein Card

General Information
Name Cal5b
Organism Conus californicus
Organism region Eastern Pacific
Organism diet piscivorous
Protein Type Wild type
Protein precursor Cal5a precursor (3983)
Notes Elliger et al. also found peptides in the venom with differential PTMs. ConoServer only records the maximally modified peptide. The other peptides found by Elliger et al. have an unmodified proline 5 (they call this peptide Cal5c), unmodfied proline 5 and 9 (called Cal5d) and unmodified prolines (called Cal5e).
