PecE and PecF, the products of two phycoerythrocyanin lyase genes (pecE and pecF) of Mastigocladus laminosus (Fischerella), catalyze two reactions: (1) the regiospecific addition of phycocyanobilin (PCB) to Cys-alpha 84 of the phycoerythrocyanin alpha-subunit (PecA), and (2) the Delta 4-->Delta 2 isomerization of the PCB to the phycoviolobilin (PVB)-chromophore [Zhao et al. (2000) FEBS Lett. 469, 9-13]. The alpha-apoprotein (PecA) as well PecE and PecF were overexpressed from two strains of M… CONTINUE READING
