Gene loss propensity for metallocarboxypeptidase E in insects is shaped by structural versatility and broader expression of metallocarboxypeptidase D but not functional importance
Christian Wegener, Julian C. Heitkamp, Vera S. Hunnekuhl
The paper investigates why the cpe gene is repeatedly lost in insects while cpd/svr is retained, finding that CPD's structural versatility and broader expression enable compensation for CPE loss.
