The inner membrane is where oxidative phosphorylation takes place in a suite of membrane protein complexes that create the electrochemical gradient across the inner membrane, or use it for ATP synthesis.
Despite the presence of elements of cytoskeleton, key features that are readily detectable in any eukaryotic genome, such as components of the nuclear pore and the spliceosome, as well as spliceosomal introns, are missing, and the entire replication machinery as well as the suite of membrane biogenesis enzymes all have telltale archaeal features [ 1].
Perhaps due to its extracellular habitat, the YLS has been forced to retain a full suite of cell membrane and wall biosynthesis genes.
Moreover, LDA inferred a stable functional module related to PULs, which included a suite of outer membrane proteins as well as the two core proteins that are known to define PULs, namely SusD- and SusC(TonB -like membrane proTonB -like Additional file 1: Table S6A).
These vacuoles have a low pH (~5.4) and contain all of the membrane and luminal markers of a mature phagolysosome, including the characteristic suite of hydrolases and the membrane NADH oxidase that generates anti-microbial oxidative burst.
Under the extracellular medium condition used, the junction potential was calculated ∼ +16 mV using the JPCalc software in the PClamp suite (Axon Instruments) and corrections of membrane potentials were made a posteriori.
Each PIP binds to a distinctive set of effector proteins and, thereby, regulates a characteristic suite of cellular processes, including membrane trafficking, cell survival/growth, cell division, and cellular motility [ 28] (See also Figure 5).
With differential membrane partitioning, a suite of siderophores could create a concentration gradient of siderophore emanating from the bacterium; such a strategy has been proposed in the bucket brigade model to iron acquisition.
Protein sequences were analyzed with multiple tools available through Biology WorkBench [ 99], including secondary structure predictions using the PELE suite of programs, alignments using ClustalW, and membrane topologies using TMHMM2.0 (scoring TM regions with probabilities > 0.2).
Intrinsic excitability refers to the propensity of a neuron to fire action potentials when exposed to an input signal, and it is directly attributable to the suite of ion channels inserted into the plasma membrane [38], [39].
