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: Given a rapid induction of Egr - 1 on stimulation with growth factors or injury , these findings may represent at least one of the molecular mechanisms underlying phenotypic modulation of smooth muscles after vascular injury .
Example Output: Egr - 1

Example Input: Two genes ( ptsI and ptsA ) that encode homologues of the energy coupling Enzyme I of the phosphoenolpyruvate - dependent sugar - transporting phosphotransferase system ( PTS ) have previously been identified on the Escherichia coli chromosome .
Example Output: Enzyme I

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
