Lycopene e-cyclase crtL-e Cyanobacteria Prochlorococcus marinus [39]... 

Two cyanobacteria also contain these enzymes (Table 106.3). Synechococcus elongatus PCC 7942 contains a functional CrtL [38]. Prochlorococcus marinus MED4 contains two lycopene cyclases, CrtL-b and CrtL-e. CrtL-b exhibits lycopene p-cyclase activity, whereas CrtL-e is a bifunctional enzyme having both lycopene s-cyclase and lycopene (3-cyclase activities [39]. The combination of these two cyclases allows the production of (3-carotene, a-carotene, and E-carotene. Both enzymes might have originated from the dupUcation of a single gene. The characteristics of this CrtL-e are somewhat different from those observed in land plants [40].

There are still very few published results on the biochemistry of this species. Like Prochlorococcus marinus, Prochlorothrix hollandica has echinenone, a specific xan-thophyll of cyanobacteria, whereas Prochloron does not have any, and the ratio Chi fl2/Chl b2 (>7.5) is appreciably higher than the values (from 4 to 8) found for Prochloron (Volkman et al., 1988). The photosynthetic equipment of this species includes a plastocyanin, the structure of...
