The Rubisco protein-enzyme is arguably the most abundance protein on Earth. The biology dogma of
transcription and translation necessitates the study of the Rubisco genes and Rubisco-like genes in various
species. Stronger correlation of fractal dimension of the atomic number fluctuation along a DNA sequence with
Shannon entropy has been observed in the studied Rubisco-like gene sequences, suggesting a more diverse
evolutionary pressure and constraints in the Rubisco sequences. The strategy of using metal for structural
stabilization appears to be an ancient mechanism, with data from the porphobilinogen deaminase gene in
Capsaspora owczarzaki and Monosiga brevicollis. Using the chi-square distance probability, our analysis
supports the conjecture that the more ancient Rubisco-like sequence in Microcystis aeruginosa would have
experienced very different evolutionary pressure and bio-chemical constraint as compared to Bordetella
bronchiseptica, the two microbes occupying either end of the correlation graph. Our exploratory study would
indicate that high fractal dimension Rubisco sequence would support high carbon dioxide rate via the Michaelis-
Menten coefficient; with implication for the control of the whooping cough pathogen Bordetella bronchiseptica,
a microbe containing a high fractal dimension Rubisco-like sequence (2.07). Using the internal comparison of
chi-square distance probability for 16S rRNA (~ E-22) versus radiation repair Rec-A gene (~ E-05) in high GC
content Deinococcus radiodurans, our analysis supports the conjecture that high GC content microbes containing
Rubisco-like sequence are likely to include an extra-terrestrial origin, relative to Deinococcus radiodurans.
Similar photosynthesis process that could utilize host star radiation would not compete with radiation resistant
process from the biology dogma perspective in environments such as Mars and exoplanets.
