Bacterial Proteases as Targets to Control Bacterial Growth

Autor: Ricardo V. Ullán, Carlos Barreiro

Publikováno v: New Weapons to Control Bacterial Growth ISBN: 9783319283661

Proteases (PRs) catalyze the cleavage of peptide bonds by hydrolysis in proteins and peptides playing crucial functions in organisms all over the phylogenetic tree. These enzymes are present in all types of bacteria and are involved in critical proce

Role of peroxisomes in the biosynthesis and secretion of β-lactams and other secondary metabolites

Autor: Juan-Francisco Martín, Carlos García-Estrada, Ricardo V. Ullán

Publikováno v: Journal of Industrial Microbiology and Biotechnology. 39:367-382

Peroxisomes are eukaryotic organelles surrounded by a single bilayer membrane, containing a variety of proteins depending on the organism; they mainly perform degradation reactions of toxic metabolites (detoxification), catabolism of linear and branc
