“What parameters characterize “life”?”

Short title: What parameters characterize “life”?

“Life” is a particular state of matter, and matter consists of diverse molecules. The state corresponding to “life” is ultimately determined by the genome sequence. In order to elucidate a parameter characterizing the state of “life”, we analyzed all the amino acid sequences from the genomes of 557 prokaryotes and 40 eukaryotes using a membrane protein prediction online tool called SOSUI. SOSUI uses only the physical parameters of the encoded amino acid sequences to make its predictions. The ratio of membrane proteins in a genome identified by the SOSUI online tool was around 23% for all genomes, indicating that this ratio constitutes one parameter of “life”.
