Molecular function and biological processes of this enzyme was obtained from the ProKnow server.
'''Function from its name'''
Molecular function of this enzyme is ATP binding. This means that the enzyme interacts selectively with ATP at the 5'end and acts as a universally important coenzyme and enzyme regulator.
On the other hand, the biological process of this enzyme is tRNA modification. This involves the covalent alteration of one or more nucleotides within the tRNA, thus leading to a change in the properties of the tRNA.

GENOMIC CONTEXT
In bacteria, the gene encoding this enzyme is known as miaA while the human and S. cerevisaea is TRIT1 and mod5 respectively. Although gene name differ in different organisms, they all synthesize enzyme of the same function.
