| Tag Information
|
|
This protein contains an N-terminal tag and may also contain a C-terminal Myc-tag. N-terminal host tags may vary (His, His-SUMO, His-B2M, GST). Tag types are determined by various factors including tag-protein stability and, therefore, are subject to change; please inquire for tag information. Additional charge for Tag removal. Tag removal service standardly refers to removal of N-terminal Tag. Any C-terminal Myc-tag may remain intact unless removal of the C-terminal Myc-tag is specifically requested. In most cases tags can be successfully removed. If the lab concludes the protein is no longer stable after tag removal then your protein will be supplied with the tag intact, and you will not be charged for tag removal service.

| UniProt Comments for OAK4
|
|
Function: Probably participates in a plant defense mechanism. Inhibitory effect on the growth and development of larvae from Helicoverpa punctigera. Has hemolytic activity. Ref.3
Domain: The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin.
Post-translational modification: Kalata-B2 is a cyclic peptide which occurs in three forms: with unmodified Trp, with Trp oxidized to form N-formylkynurenine and with Trp oxidized to form kynurenine. Oxidation is enhanced by exposure to sunlight.
Sequence similarities: Belongs to the cyclotide family. Moebius subfamily.
Mass spectrometry: Molecular mass is 2955.4 Da from positions 67 - 95. Determined by ESI. Ref.4Molecular mass is 2987.4 Da from positions 67 - 95. Determined by ESI. With N-formylkynurenine. Ref.4Molecular mass is 2959.4 Da from positions 67 - 95. Determined by ESI. With kynurenine. Ref.4
