Sulcia muelleri differs from them because it has a secondary symbiont capable of synthesizing methionine and histidine, capabilities that have been lost in S. muelleri.
"The rig was not equipped with a secondary system capable of securing the well in the absence of the primary BOP controls," said a federal report on the accident.
Baltimore has not allowed more than one touchdown to a quarterback since Week 1. Russell Wilson (SEA) vs. Arizona — The Cardinals' secondary is capable of playing the pass tough (14 FPPG to QBs over the last three weeks).
PA is considered an important secondary messenger capable of modulating pathways responsible for cell survival and proliferation, such as the mTOR and Raf-1 signaling cascade [29] [32].
Thorectes lusitanicus acts as a secondary disperser, capable of partially consuming (Fig. 1) dragging and burying a high number of viable acorns of both Quercus species during their reproductive period of activity (autumn-winter).
In addition, all fragile DNA sequences examined so far demonstrate significantly high flexibility [ 17], and are comprised of AT-rich flexislands islands that can readily fold into stable secondary structures capable of perturbing DNA replication [ 17, 18].
This observation raises doubts about both the role of C. ruddii in the symbiotic relationship with its host and the absence of a secondary symbiont capable to provide the rest of necessary nutrients to complement the unbalanced insect diet.
Cell necrosis was somehow expected since during antagonism/mycoparasitism T. atroviride strain P1 typically releases trichorzianines, <3 kDa secondary metabolites capable of directly killing cells by destructing the plasma membrane [ 15].
Ybt emerges from these studies as a multifunctional virulence-associated secondary metabolite capable of forming a non-protein, copper-centered catalyst that helps bacteria resist the respiratory burst of activated phagocytes.
The MFS transporters include drug efflux systems, organophosphate:phosphate exchangers and oligosaccharide:H+ symport permeases and are single-polypeptide secondary carriers capable only of transporting small solutes in response to chemiosmotic ion gradients [ 36]. Figure 1 shows blocks of synteny shared between T. equi and B. bovis, T. parva, or T. annulata.
