Question

An uncharged protein (P) has an Asp in position 23 with a molecular weight of 6501 Da, as determined by mass spectrometry. The uncharged mutant of this protein (P') contains a single amino acid substitution with Asn at position23. The molecular weight of P', as determined by mass spectrometry (rounded off to one decimal place) is __ Da.

Explanation

Evidence for enzyme kinetics indicates substrate binding and catalytic efficiency determine reaction rates. Option NAT aligns with this, as it reflects active-site specificity and regulation, reflecting standard interpretations in biochemistry.
