Definition: 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.
Input:  Using the center domain ( residues 1 - 73 and 121 - 167 ) alone , the highest structural similarity is found with the human beta 2 - adaptin appendage domain ( PDB code 1E42 , Z score = 7 . 1 , r . m . s . deviation = 2 . 5 A for 85 structurally aligned residues , residues 1 - 12 , 14 - 30 , 44 - 47 , 58 - 72 , 122 - 133 and 135 - 160 of P . aeruginosa RdgC chain A and residues 838 - 841 , 848 - 880 , 885 - 906 and 912 - 967 of the human beta 2 - adaptin appendage domain chain A ) ( 19 ) .
Output:
P . aeruginosa
