Lycopene beta cyclase, chloroplastic (LCY1), Arabidopsis thaliana, recombinant

Organism: Arabidopsis thaliana (Mouse-ear cress). Source: E.coli. Expression Region: 81-501aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: QVVDLAIVGG GPAGLAVAQQ VSEAGLSVCS IDPSPKLIWP NNYGVWVDEF EAMDLLDCLD TTWSGAVVYV DEGVKKDLSR PYGRVNRKQL KSKMLQKCIT NGVKFHQSKV TNVVHEEANS TVVCSDGVKI QASVVLDATG FSRCLVQYDK PYNPGYQVAY GIVAEVDGHP FDVDKMVFMD WRDKHLDSYP ELKERNSKIP TFLYAMPFSS NRIFLEETSL VARPGLRMED IQERMAARLK HLGINVKRIE EDERCVIPMG GPLPVLPQRV VGIGGTAGMV HPSTGYMVAR TLAAAPIVAN AIVRYLGSPS SNSLRGDQLS AEVWRDLWPI ERRRQREFFC FGMDILLKLD LDATRRFFDA FFDLQPHYWH GFLSSRLFLP ELLVFGLSLF SHASNTSRLE IMTKGTVPLA KMINNLVQDR D. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Catalyzes the double cyclization reaction which converts lycopene to beta-carotene and neurosporene to beta-zeacarotene.
