Cell-wall lytic enzymes at sporulation and spore germination in Bacillus species.
When washed sporulating cells of Bacillus cereus were incubated in buffer a t 37" in the presence of toluene, a partial autolysis occurred resulting in the freeing of mature and immature spores. The autolysate contained lytic enzymes which attacked vegetative cells and cell-wall preparations, releasing hexosaminecontaining peptides of characteristic constitution. The most active enzyme preparat...
متن کاملResuscitation-promoting factors are cell wall-lytic enzymes with important roles in the germination and growth of Streptomyces coelicolor.
Dormancy is a common strategy adopted by bacterial cells as a means of surviving adverse environmental conditions. For Streptomyces bacteria, this involves developing chains of dormant exospores that extend away from the colony surface. Both spore formation and subsequent spore germination are tightly controlled processes, and while significant progress has been made in understanding the underl...
متن کاملAntibiotics produced by Streptomyces.
Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and its shape resembles filamentous fungi. The morphological differentiation of Streptomyces involves the formation of a layer of hyphae that can differentiate into a chain of spores. The most interesting property of Streptomyces is the ability to produce bioactive secondary metabolites, such as antifungals, a...
متن کاملThe biochemistry of the Actinomycetales: studies on the cell wall of Streptomyces fradiae.
In order to gain some information on the comparative biochemistry of the Streptomyces, an investigation of the nature of the cell wall has been undertaken. There are only few data relating to the chemical composition of the actinomycetes. Thus, Avery and Blank (1954) found that representative species of Actinomyces, Nocardia, Streptomyces, and Micromonospora were all devoid of chitin and cellul...
متن کاملExtracellular proteolytic enzymes produced by human pathogenic vibrio species
Bacteria in the genus Vibrio produce extracellular proteolytic enzymes to obtain nutrients via digestion of various protein substrates. However, the enzymes secreted by human pathogenic species have been documented to modulate the bacterial virulence. Several species including Vibrio cholerae and V. vulnificus are known to produce thermolysin-like metalloproteases termed vibriolysin. The vibrio...
