Flotillin proteins are ubiquitous in all kingdoms of life; they have been studied extensively in the model organism Bacillus subtilis and the localisation protein FloT has been described in this model as having a lateral distribution in cells. NfeD is a protein that was first isolated from Sinorhizobium meliloti and was identified as a factor that enhanced nodulation. In B. subtilis these proteins co-localise. We aimed to describe the localisation of these proteins in the filamentous bacteria Streptomyces coelicolor in order to infer functions of these proteins and identify any role that they may play in hyphal growth and development. This study used cloning techniques involving the use of restriction enzymes and ligase to translationally fuse the SCO3607 and SCO3608 genes to mCherry and GFP respectively. We observed the localisation of FloT in samples grown after 24h, 26h, and 72h with the use of fluorescence microscopy. FloT was visualised as GFP foci or diffuse GFP expression within the samples. This research has shown that FloT localises in a random lateral manner in vegetative hyphae in S. coelicolor.
