An unexpectedly branched biosynthetic pathway for bacteriochlorophyll b capable of absorbing near-infrared light
Chlorophyllous pigments are essential for photosynthesis. Bacteriochlorophyll (BChl) b has the characteristic C8-ethylidene group and therefore is the sole naturally occurring pigment having anExpand

A heterogeneous tag-attachment to the homodimeric type 1 photosynthetic reaction center core protein in the green sulfur bacterium Chlorobaculum tepidum.
The 6xHis-tag-pscA gene, which was genetically engineered to express N-terminally histidine (His)-tagged PscA, was inserted into a coding region of the recA gene in the green sulfur bacteriumExpand
