What Amino Acid Residue Receives a Phosphoryl Group from P-Type

Question

What amino acid residue receives a phosphoryl group from P-type ATPases?
A) serine
B) tyrosine
C) cysteine
D) lysine
E) aspartate

Accepted Answer

P-type ATPases are known for their mechanism of autophosphorylation on an aspartate residue as part of their function in transporting ions across membranes. This phosphorylation is a key step in their catalytic cycle.
