additional information

insertional inactivation of pcyA is not possible in wild-type Synechococcus sp. strain PCC 7002 due to lethality of the mutant, but in a variant heterologously expressing HY2 from Arabidopsis thaliana encoding a phytochromobilin:ferredoxin oxidoreductase

malfunction

because PcyA and PebA, EC 1.3.7.6/1.3.7.3, utilize the same substrate, biliverdin IXalpha, severe overexpression of pebA can limit the availability of phycocyanobilin, which appears to be required for viability when cells are grown in continuous light
