There is no clear complete sequence for Act d 13. Sirvent S, et al., 2014 in a note in JACI show purification and biochemical characterization, but only four peptide sequences (by MS) that show partial sequence identities to a mustard 2S (Sin a 1, uniprot P15322) and to Brassica rapa or napus. The paper by Sirvent, Canto et al., 2014 Allergy) does not show sequence identity or refer to sequence. Neither does the paper by Nilsson et al., Ped Allergy and Immunology 2015. Unless a sequence can be determined and published that clearly represents this 2S albumin from kiwi, the identity of the allergen is not certain. However a search of protein databases shows an 8 amino acid segment "gpqqqhrl" as entry Accession C0HJG0. That is not enough for specific identity. REG 1 Aug 2018
