Immobilization of penicillin G acylase using permeabilized Escherichia coli whole cells within chitosan beads.

Research in pharmaceutical sciences

Bagherinejad MR, Korbekandi H, Tavakoli N, Abedi D.
PMID: 23181084
Res Pharm Sci. 2012 Apr;7(2):79-85.

Entrapment of permeabilized whole cells within a matrix is a common method for immobilization. Chitosan possesses distinct chemical and biological properties, which make it a suitable matrix for entrapment and immobilization of penicillin G acylase (PGA). In the first...

Positional Variance in NMR Crystallography.

Journal of the American Chemical Society

Hofstetter A, Emsley L.
PMID: 28146348
J Am Chem Soc. 2017 Feb 22;139(7):2573-2576. doi: 10.1021/jacs.6b12705. Epub 2017 Feb 08.

We propose a method to quantify positional uncertainties in crystal structures determined by chemical-shift-based NMR crystallography. The method combines molecular dynamics simulations and density functional theory calculations with experimental and computational chemical shift uncertainties. In this manner we find...

A series of six novel metallocenyl-7-ADCA (metallocenyl = ferrocenyl or ruthenocenyl; 7-ADCA = 7-aminodesacetoxycephalosporanic acid) conjugates were synthesized and their antibacterial properties evaluated by biochemical and microbiological assays. The ruthenocene derivatives showed a higher level of inhibition of DD-carboxypeptidase...
