Aerolysin (aerA) [68], toxin A(rtxA) [69], layer A (vapA) and secretion systems types II (T2SS) (exeAB and exeC-N operons), T3SS (ascV, aopP, aopH, ascC and aexT genes), T4SS (traB, traC, traD, traE, trbJ, traA, traF, traG, traH, traI, traJ and traK genes, with...
Metallocluster enzymes are one of the most ubiquitous family of enzymes involved in natural product biosynthesis and are of great biotechnological importance. However, the functional expression of recombinant metallocluster enzymes in live cells is often challenging and represents a major bottleneck. The ...
wt. subunits of unknown function. Overall, these diverse structures have revealed that (i) the HB RC-PS is the simplest light–energy transducing complex yet isolated and represents the closest known homolog to a common homodimeric RC-PS ancestor; (ii) the symmetrically localized Ca2+-binding ...
