Phytochelatins (PCs) are small enzymatically synthesized peptides having a general structure of [poly-(gamma-Glu-Cys)n-Xaa] polymers where n equals 2 to 11. They are found in all plant species investigated, a few fungal species, and some marine diatoms, where they act as high affinity metal chelators. In iso-phytochelatins, the polymer is capped C-terminally by a serine, glutamine, glutamic acid or in homo-phytochelatin with beta-alanine.SEQUENCE: H-gamma-Glu-Cys-gamma-Glu-Cys-beta-Ala-OH (trifluoroacetate salt)ONE-LETTER SEQUENCE: gammaE-C-gammaE-C-betaAMOLECULAR FORMULA: C19H31N5O10S2MOLECULAR WEIGHT: 553.60STORAGE CONDITIONS: -20 5 CCAS REGISTRY NUMBER: SYNONYMS: H-γ-Glu-Cys-γ-Glu-Cys-beta-Ala-OHRESEARCH AREA: MiscellaneousREFERENCES:Lee, S. et al.
