Purification and properties of an extracellular agarase from Alteromonas sp.strain C-1
Article Abstract:
The different mechanisms of agar hydrolysis used by marine bacteria are studied. Experiments involved the isolation of a few agarolytic strains which were identified as Alteromonas sp. strain C-1. Extracellular agarase was produced at high levels by the strain in the presence of agar. However, this production was repressed by glucose. Anion-exchange chromatography and gel filtration purified the enzyme to homogeniety. An overall yield of 45% was acquired.

EhRho1, a RhoA-like GTPase of Entamoeba histolytica, is modified by clostridial glucosylating cytotoxins
Article Abstract:
A study reveals that the EhRho1 is a preferred substrate for glucosylation by Clostridium difficile toxin B and Clostridium novyi alpha-toxin in vitro, although the holotoxins do not affect the Entamoeba histolytica trophozoites in culture. It is shown that lethal toxin from Clostridium sordelli did not glucosylate EhRho1 but labeled several other substrate proteins in lysates from Entamoeba histolytica.
