(-) Compounds

Molecule 1 - PROTEIN MRIB-NH2
    Chains: A
    Engineered: YES
    Other Details: THIS PEPTIDE WAS CHEMICALLY SYNTESIZED. THIS SEQUENCE OCCURS IN CONUS MARMOREUS (MOLLUSC-HUNTING CONE SNAIL). HOWEVER, THE C-TERMINUS HAS BEEN AMIDATED WHEREAS IT EXISTS AS A FREE-ACID IN THE NATIVE FORM.
    Synthetic: YES

NMR Structure(hide GO term definitions)
Chain A   (CT1B_CONMR | P58810)
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
