Structure of the Ergothioneine‐Biosynthesis Amidohydrolase EgtC [PDF]
ChemBioChem, 2015 AbstractThe ubiquitous sulfur metabolite ergothioneine is biosynthesized by oxidative attachment of a sulfur atom to the imidazole ring of Nα‐trimethylhistidine. Most actinobacteria, including Mycobacterium tuberculosis, use γ‐glutamyl cysteine as a sulfur donor. In subsequent steps the carbon scaffold of γ‐glutamyl cysteine is removed by the glutamine

Penicillin Amidohydrolases in Fungal Autolysis [PDF]
Microbiology and Immunology, 1989 AbstractThe production of penicillin G and penicillin V amidohydrolases or acylases (E.C.3.5.1.11) was studied during the autolysis of filamentous fungi in a mineral medium, and in the same medium with phenoxyacetic acid as inducer. In all the studied fungi, enzymes showing penicillin G and penicillin V amidohydrolase activities were found.

Phenoxymethylpenicillin amidohydrolases from Penicillium chrysogenum [PDF]
FEBS Letters, 1996 A phenoxymethylpenicillin amidohydrolase which hydrolyses phenoxymethylpenicillin to 6‐aminopenicillanic acid (6‐APA) has been isolated from two species of Penicillium chrysogenum. The amidohydrolase had a molecular mass of approx. 42 kDa. Its activity with benzylpenicillin as substrate was only 1.5% of that with phenoxymethylpenicillin and it was ...
