Given the task definition, example input & output, solve the new input case.
In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.
Example: Sox - 4 is important for very early B - cell differentiation , while TCF - 1 / LEF - 1 play a crucial role in early thymocyte development 
Output: TCF - 1
The gene, TCF - 1 has been tagged as protein since it plays a crucial role in early thymocyte development.

New input case for you:  Using the tip domain ( residues 74 - 120 ) alone , the ATPase domain of bovine Hsc70 chaperone shows highest structural similarity ( PDB code 1BA1 , Z score = 4 . 8 , r . m . s . deviation = 1 . 7 A for 45 structurally aligned residues , residues 76 - 120 of P . aeruginosa RdgC chain A and residues 230 - 253 and 256 - 276 of the Hsc70 ATPase domain ) ( 21 ) .
Output:
P . aeruginosa
