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: 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: The yeast genome contains a single ORD1 gene that resides on chromosome XI .
Example Output: ORD1 gene

Example Input: Biochemical studies have identified a cellular non - P element - encoded DNA binding protein , termed the inverted repeat binding protein ( IRBP ) , that specifically interacts with the outer half of the 31 - bp terminal inverted repeats .
Example Output:
P element
