Table 5.
Number of structures in the PDB derived from mesophilic or extremophilic prokaryotes (as identified by the Prokaryote Growth Temperature database), grouped by reported temperature of crystallization (Tc) in the PDB. The numbers in parentheses indicate the number of structures in a given growth category and Tc range as a percentage of all structures crystallized in the given Tc range
