WebOct 21, 2024 · Now, cis ligands share the d and s portions of those hybrid orbitals, but trans ligands share d, s, and one p portion of those hybrid orbitals. So trans ligands are automatically competing more for sigma bonding electron density than cis ligands. Good trans influencers "outcompete" bad ones, which is the origin of the trans influence series.

WebAug 28, 2024 · Evidently, ligands may also influence the kinetics or thermodynamics of their cis neighbors. All of these phenomena are independent of the metal center, but do depend profoundly on the geometry of the metal (more on that shortly). Kinetic trans and cis effects are shown in the figure below. WebAug 24, 2011 · This extended ligand binding in cis by C-type lectin-like receptors to structurally unrelated Ig-like receptors suggested that cis binding of MHC-I impacts numerous hematopoietic cell types and is not restricted to NK cells. Similarly to Ly49, the association between MHC-I and LILRB/PIR-B receptors in cis is constitutive [ 14 ].
