Expression of the fxsA-gfp fusion is from the fxsAp109 promoter, the fusion protein contains the first 120 residues of FxsA, a linker of the amino acids ACSRLE, followed by the N-terminal methionine residue of GFP. Probably an integral plasma membrane protein, but not sure if that annotation can be made based on the data in the paper.	complete
