Ans 1) In De novo purine biosynthesis, the first and committed step is the displacement of pyrophosphate by ammonia to produce 5-phosphoribosyl-1-amine is catalyzed by the enzyme Glutamine amidotransferase.
Even in the conversion of IMP to AMP and GMP , this enzyme comes into picture. XMP (Xanthosine monophosphate) is converted to GMP (Guanosine monophosphate) by XMP-glutamine amidotransferase.

3. Draw an the mechanism showing how the glutamine-PRPP amidotransferase adds nitrogen to PRPP in the first comitted step of purine nucleotide biosynthesis. Compare this reaction with the addition of orotate to PRPP in the 5th step of purine biosynthesis.

6. Draw the structure of UMP. Following standard convention, number the ribose and purine rings. Assume you used isotopically labeled C enriched aspartate as a starting material for the synthesis of this coupound. Based on your knowledge of the ring assembly identify the carbon atoms in the ring that will be 13C-enriched.

The picture below has species I-IV (teg = species in this case)
and traits/characteristics (a-j). Classify species I-IV based on
the traits (a-j) and draw a parsimony tree.
What effect would it have on your classification of the species,
if it was based on the amount of shared characteristics/traits?
Does it change anything if 0 (zero)...
