Diffusion coefficient of carboxysome

Range 3.85e-1 Theoretical 4.58e-5 Observed µm^2/sec
Organism Cyanobacteria Synechococcus elongatus PCC 7942
Reference Savage DF, Afonso B, Chen AH, Silver PA. Spatially ordered dynamics of the bacterial carbon fixation machinery. Science. 2010 Mar 5 327(5970):1258-61 p.1259 left column and fig 3A and middle columnPubMed ID20203050
Method Observed-Fluorescence microscopy. Theoretical-Using cytoplasmic parameters (Elowitz et al. 1999 PMID 9864330) and a mean particle radius of 50nm, researchers estimate a theoretical value of D=0.385µm^2/s, four orders of magnitude greater than the observed.
