| Abstract: | Synechocystis sp. PCC 6803 lacks a gene for the any known
types of lycopene cyclase. Recently, we reported that Sll0659
(unknown for its function) from Synechocystis sp. PCC6803 shows
similarity in sequence to a lycopene cyclase gene—CruA from
Chlorobium tepidum. To test, whether sll0659 encoded protein serves
as lycopene cyclase, in this study, we investigated the carotenoids of
the wild types and mutants. In the sll0659 deleted mutant, there is no
blockage at the lycopene cyclization step. Our results demonstrate that
sll0659 does not affect lycopene cycilzation. However, the
ultrastructure of mutants suggests the involvement or necessity of
sll0659 in the cell division. |
