Question

news flash: life was just discovered on Mars! scientists have begun to examine Martian life and find that it is cellular, and probabaly driven from an early meteorite- delivered colonization event from the Earth when the planets were both still young .analysis of Martian cell reveals that Mars life uses the same DNA and RNA that we do, but all the enzyme catalysts are also made of nucleic acids, rather than of proteins. you find the Martian equivalent to the Terran protein restriction endonuclease Sau 3ai. Propose a reasonable catalytic mechanism for how this Marti enzyme converts its substrate into product? Please give me the answer in details

Explanation / Answer

Unlike the earth enzymes, the Martian enzymes don not contain proteins , rather they are made up of nucleus acids, I.e. Either DNA or RNA . There are no additional catalytic sites made up of amino acids as there are in the earth enzymes. In the place of the amino acids at their active sites, these enzymes will have short stretches of nucleotide sequences that would recognise for a particular substrate. These sequences would be conserved sequences that would be specific for a specific substrate, imparting earth enzyme like specificity to these enzymes. Also, just like the earth enzymes, these catalysts would lower the activation energy of the substrate to enzyme formation and thus carry out the reaction.
