Prochlorococcus, a marine photosynthetic prokaryote of global significance

Article Abstract:

Prochlorococcus is a photosynthetic marine prokaryote that has drawn the interest of researchers worldwide due to its unique cellular features. Dubbed as the smallest photosynthetic organism known to man, the bacteria has an estimated spherical diameter of 0.5 to 0.7 micro millimeters. Studies have shown that prochlorococcus strains possess a pigment complement consisting of divinyl derivatives of chlorophyll A that is unique to its genus. Researchers have also reported that these microorganisms have an inert capability to proliferate in nutrient-depleted areas.

Acylation of Escherichia coli hemolysin: a unique protein lipidation mechanism underlying toxin function

Article Abstract:

A study was conducted on the acylation of the hemolysin (HlyA) of Escherichia coli to determine its posttranslational mechanism of modification and its relationship to protein lipidation in prokaryotes and eukaryotes. Results showed that the acyltransferase of HlyA is different from the that of any prokaryotes, but seems to be related to a few eukaryotic proteins. The mechanism involved in the acyltransferase activity indicates that protein lipidation is important in the regulation of protein-protein interactions.
