Characterization of a New M4 Metalloprotease With Collagen-Swelling Ability From Marine Strain 12613.

The ocean harbors a variety of bacteria that contain huge protease resources and offer a great potential for industrial and biotechnological applications. Here, we isolated a protease-secreting bacterium strain 12613 from Atlantic seawater and purified a protease VP9 from strain 12613. VP9 was identified as a metalloprotease of the M4 family.

gen. nov., sp. nov., isolated from Antarctic rotten seaweed.

A Gram-stain-negative, pink-pigmented, rod-shaped, non-flagellated, aerobic bacterium, designated strain SM1701, was isolated from a rotten seaweed collected off Fildes Peninsula, King George Island, West Antarctica. The strain grew at 4-30 °C, pH 6.0-8.

Atomic Force Microscopy of Side Wall and Septa Peptidoglycan From Reveals an Architectural Remodeling During Growth.

Peptidoglycan is the fundamental structural constituent of the bacterial cell wall. Despite many years of research, the architecture of peptidoglycan is still largely elusive. Here, we report the high-resolution architecture of peptidoglycan from the model Gram-positive bacterium .
