additional information
a transposon mutant of gene bchP encoding geranylgeranyl-bacteriochlorophyll reductase possesses a structurally modified photosystem assembled with bacteriochlorophyll esterified with geranylgeraniol, rather than with phytol

additional information
construction of a a hybrid gene consisting of the 5'half of Rhodospirillum rubrum bchP and the 3' half of Rhodobacter sphaeroides bchP, with the fragments fused as for bchPDELTAx, possesses neither geranylgeranyl-bacteriopheophytin reductase nor geranylgeranyl-bacteriochlorophyll a reductase activity. When complenmentation of the mutant is attempted with a similar fusion between the 5' half of Rhodobacter sphaeroides bchP and the 3' half of Rhodospirillum rubrum bchP, expressed in plasmid pSK1bchPS/PR, not only is BpheaP biosynthesis restored, but approximately 10% of the Bchl present is found to be esterified with dihydro-GG. Complete restoration of both BchlaP and BpheaP synthesis is achieved by using the positive control plasmid, pSK1bchPS/PS, in which the two relevant Rhodobacter sphaeroides bchP fragments are reunited

additional information
the bchP mutant T6G5 of purple photosynthetic bacterium Rhodobacter sphaeroides is blocked in the terminal hydrogenation steps of bacteriochlorophyll a biosynthesis. The mutant possesses only bacteriochlorophyll esterified with geranylgeraniol and has a reduced cellular level of the light-harvesting LH2 complex. Upon heterologous expression of the Synechocystis bchP homologue encoded by gene chlP, not only are hydrogenated forms of geranylgeranyl bacteriochlorophyllide a (bchlaGG) detectable, but the level of LH2 is increased, phenotype, overview

generation of a gene CT2256 deletion mutant, which almost shows no apparent phenotype compared to the wild-type. The purple bacterium Rhodobacter capsulatus mutant strain DB391 defective in the bchP gene is partially complemented with the CT2256 gene, bacteriochlorophyllide a is synthesized in the mutant in addition to accumulating other intermediates, phenotype, overview
