Question
Chapter 24, Problem 10P
Interpretation Introduction
Interpretation:
The lipid synthetic pathways that would be affected by abnormally low levels of CTP should be identified.
Concept Introduction:
Cytidine triphosphate abbreviated as CTP is a pyrimidine nucleoside triphosphate which is much like ATP. Only difference is the base, which the base used in CTP is cytosine. CTP acts as a coenzyme reactions like synthesis of glycerophospholipids and glycosylation of proteins.

Inducers and Inhibitors of AEP.
Short peptides such as legumain stabilization and activity modulation (LSAM) domain and αvβ3 integrin could enhance the activity of AEP. LSAM domain known as the prodomain of AEP blocks substrate binding before activation. This prodomain has a helical structure and two independent peptides. One is an activation peptide (AP, K287 to N323), and the other is a LSAM domain. LSAM domain remains even after AP is cleaved and released from protease at neutral pH via electrostatic interaction. AEP without LSAM domain has a lower melting temperature than AEP with LSAM domain [77, 117]. Another short peptide, αvβ3 integrin, can directly interact with AEP, and after forming a complex, the optimal pH for AEP activity is increased from 5.5 to 6.0. It indicates that αvβ3 binding could induce conformational stabilization of AEP accompanied by deprotonated C189. αvβ3 does not directly interact with the AEP active site; however, AEP docks to the αvβ3 RGD-binding site…
