F. nucleatum - California State University, Long Beach
... It is possible that some F. nucleatum strains have sialylated LPS but do not contain the entire putative Neu5Ac operon in which case the source of Neu5Ac is likely exogeneous. Out of the strains that do contain the operon, each can have any combination of six genes of the Neu5Ac operon with the poss ...

Operon Control of Gene Expression - Glebe
... An operon is a system which controls how genes are switched on and off together, as a unit. It is not the proteins that are produced that define an operon, an operon is a mechanism of control. An operon always contains several structural genes, an operator, and a promoter. ...
