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:  Here , we report the crystal structure of P . aeruginosa RdgC as determined by the multiwavelength anomalous diffraction ( MAD ) method of X - ray crystallography .
Output:
P . aeruginosa
