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 Input:  Both flavoproteins are active as AhpC reductases and mediate electron transfer , resulting in the NADH - dependent reduction of hydrogen peroxide and cumene hydroperoxide .
Example Output: AhpC reductases

Example Input:  Vertebrate U6 small nuclear RNA ( snRNA ) loci exemplify a novel class of polymerase III - transcribed genes that lack an intragenic control region ( ICR ) .
Example Output: polymerase III

Example Input:  Our results showed that the 5 - hydroxytryptamine ( 5 - HT ) content in platelets was : ( 1 ) increased in the subgroup of anti - social alcoholics ; ( 2 ) transiently and differently altered in alcoholics compared to opiate addicts ; and ( 3 ) lowered in drinking alcoholics and normal in alcoholics who were drinking as well as smoking ( that may occur via MAO - B inhibition by smoke ) .
Example Output:
MAO - B
