“…[16][17][18][19][20][21][22] Due to various of complex sites in peptide monomer including the nitrogen atom at the N-terminus, the carboxylate group at the C-terminus, and the oxygen or nitrogen atoms presenting in the backbone chain, it is difficult to determine which complex site is for sodium binding. The site is a competitive complexation determined by the particular solvent condition.…”

Although the existing design principle of full-sequence ionic complement is convenient for the development of peptides, it greatly constrains the exploration of peptides with other possible assembly mechanisms and different yet essential functions. Herein, a novel designed half-sequence ionic complementary peptide (referred to as P9), AC-Pro-Ser-Phe-Asn-Phe-Lys-Phe-Glu-Pro-NH 2 , is reported. When transferred from pure water to sodium chloride solution, P9 underwent a dramatic morphological transformation from globular aggregations to nanofibers. Moreover, the rheological experiment showed that the P9 could form a hydrogel with a storage modulus of about 30 Pa even at very low peptide concentration (0.5% (wt/vol)). The P9 hydrogel formed in salt solution could recover in a period of about 1,800 sec, which is faster than that in the pure water. The data suggested that the half-sequence, ionic complementary peptide might be worthy of further research for its special properties.

“…[101] Changing the peptide to GlyGlu affords a structure with two ligands coordinated through the carboxylates (O10, O11, and O13, O14) with a coordination sphere that is described as a distorted square antiprism due to the coordination angles of the carboxylates (53.27 o and 53.66 o , respectively) ( Table 2, entry 2). [102] Changing the metal to Co II affords a configuration where the Co II ions are positioned at the vertices of the Co-L-GlyGlu ladders ( Table 2, entry 3). [65] The ladders are strongly connected via hydrogen bonds involving the amino group and carboxylate of GlyGlu in the neighboring ladders.…”

Metal organic frameworks (MOFs) are extended structures composed of a network of organic ligands and metal ions or clusters connected to each other via coordination bonds. The numerous choices of organic ligands and metal coordination geometries have led to the construction of porous MOFs with various compositions, network topologies, pore sizes and shapes and they possess high surface areas and low densities. The structures of MOFs can be tailor-tuned in such a way that any desired ligand or/and metal ion can be incorporated; this has given to researchers the advantage of designing MOFs for a targeted application. Within this review, we overview recent examples of a sub-class of MOFs namely biologically derived MOFs (bio-MOFs), made of multifunctional and commercially available biologically derived ligands (bio-ligands) such as: amino acids, peptides, nucleobases and saccharides and focus on their coordination chemistry with a variety of metals. Central to this review are four tables detailing the coordination modes of bio-ligands to metals, along with a visual representation of the bio-MOF that is subsequently formed. Through the detail analysis of these structures, we highlight the structural impact of these ligands on the structure, and their contribution to the MOFs properties and applications. Finally, we showcase the potential of bio-MOFs in several research areas such as CO2 capture, separation, catalysis, drug delivery and sensing.

“…Gasque et al synthesized two MBioFs made from the connection of Pb(II) or Cd(II) ions through GlyGlu ligands. 46 The first material has a 2-D metal-peptide framework, in which both carboxylate groups of each Glu residue coordinate to four Pb(II) ions in a tridentate mode. The second is a 3-D porous MBioF, [Cd(GlyGlu) 2 ]Á3H 2 O, that has 1-D channels (Fig.…”
