However it is now known that not all S. aureus are coagulase-positive. It is also produced by Yersinia pestis. Coagulase reacts with prothrombin in the blood. The resulting complex is called staphylothrombin, which enables the enzyme protease to convert fibrinogen, a plasma protein produced by the liver, to fibrin.oagulase is tightly bound to the surface of the bacterium S. aureus and can coat its surface with fibrin upon contact with blood. The fibrin clot may protect the bacterium from phagocytosis and isolate it from other defenses of the host.
The definition of a Green Zone varies from community to community, but there is a common concept: a Green Zone designation provides a local framework to protect the environmental and economic health of a community heavily affected by local pollution. Read more about Green Zones in this LA Times article.he Environmental Protection Agency endorsed the Green Zone concept at a forum at the White House in December 2010. CBE was there, along with other environmental justice and indigenous groups from around the country.
Prof. Stephen A. Nelson. Coastal Zones. A coastal zone is the interface between the land and water. These zones are important because a majority of the world's population inhabit such zones. Coastal zones are continually changing because of the dynamic interaction between the oceans and the land.Waves and winds along the coast are both eroding rock and depositing sediment on a continuous basis, and rates of erosion and deposition vary considerably from day to day along such zones. The tidal bulges result in a rhythmic rise and fall of ocean surface, which is not noticeable to someone on a boat at sea, but is magnified along the coasts. 2  Usually there are two high tides and two low tides each day, and thus a variation in sea level as the tidal bulge passes through each point on the Earth's surface.
