| replacing the axial ligand tyrosine 75 or its hydrogen bond partner histidine 83 minimally affects hemin acquisition by the hemophore hasap from pseudomonas aeruginosa. | hemophores from pseudomonas aeruginosa (hasap), serratia marcescens (hasasm), and yersinia pestis (hasayp) bind hemin between two loops. one of the loops harbors conserved axial ligand tyr75 (y75 loop) in all three structures, whereas the second loop (h32 loop) contains axial ligand his32 in hasap and hasasm, but a noncoordinating gln32 in hasayp. binding of hemin to the y75 loop of hasap or hasasm causes a large rearrangement of the h32 loop that allows his32 coordination. the q32 loop in apo-h ... | 2014 | 24625274 |

| studies on production and biological potential of prodigiosin by serratia marcescens. | efficacy of serratia marcescens for pigment production and biological activity was investigated. natural substrates like sweet potato, mahua flower extract (madhuca latifolia l.), and sesam at different concentrations were taken. as a carbon source microorganism favored potato powder was followed by sesam and mannitol, and as nitrogen source casein hydrolysate was followed by yeast and malt extract. the effect of inorganic salts on pigment production was also studied. at final optimized composit ... | 2014 | 24781979 |
| cyclic-amp inhibition of fimbriae and prodigiosin production by serratia marcescens is strain-dependent. | the cyclic-nucleotide 3',5'-cyclic amp (camp) is an ancient and widespread regulatory molecule. previous studies have shown that fimbria production and secondary metabolite production are inhibited by camp in the prokaryote serratia marcescens. this study used genetic manipulations to test the strain specificity of camp-cyclic-amp receptor protein regulation of fimbria production and of the red pigment, prodigiosin. a surprising amount of variation was observed, as multicopy expression of the ca ... | 2014 | 24619531 |

| antimicrobial effect and membrane-active mechanism of tea polyphenols against serratia marcescens. | in this study, we investigated the antimicrobial effect of tea polyphenols (tp) against serratia marcescens and examined the related mechanism. morphology changes of s. marcescens were first observed by transmission electron microscopy after treatment with tp, which indicated that the primary inhibition action of tp was to damage the bacterial cell membranes. the permeability of the outer and inner membrane of s. marcescens dramatically increased after tp treatment, which caused severe disruptio ... | 2014 | 23979827 |
| identification of a serratia marcescens virulence factor that promotes hemolymph bleeding in the silkworm, bombyx mori. | injection of culture supernatant of serratia marcescens, a gram-negative bacterium pathogenic to a wide range of host animals including insects and mammals, into the hemolymph of silkworm (bombyx mori) larvae led to continuous flow of the hemolymph (blood of insects) from the injection site. the amount of hemolymph lost within 60 min reached 15-20% of the total larval weight. using a bioassay with live silkworms, we purified serralysin, a metalloprotease that requires divalent cations for its ac ... | 2014 | 24530643 |
| draft genome sequence of serratia marcescens strain lct-sm166, a space flight strain with a specific carbon source utilization pattern. | serratia marcescens has been detected in space habitats. to explore the influence of the space flight environment on this bacterium, we investigated the genome sequence of lct-sm166, which was isolated after space flight and has a specific carbon source utilization pattern. | 2014 | 24526644 |
