Upon sulfate-deficiency, SQDG is almost completely degraded, whereby a major intracellular S-source for protein synthesis is ensured at an early stage, accompanied by an increase in the PG content [ 19 ]. However, behavior of SQDG metabolism and its physiological significance have never been examined under S-starved conditions in any freshwater microbes other than C. In this study, effects of S-starvation on SQDG metabolism was investigated in freshwater microbes such as cyanobacteria, Synechococcus and Synechocystis, and a green alga, Chlorella kessleri, to gain more insight into the taxonomical distribution of SQDG degradation ability. Obtained results will be discussed from an evolutionary aspect for oxygenic photosynthetic organisms. Materials and methods Strains and growth conditions The strains used were C. S-free medium was prepared by replacing sulfate with chloride, i. When needed, C. The labeled cells were washed three times with the S-free medium, and then shifted to 32S-replete or S-free conditions for further growth. Determination of pigment and lipid contents The contents of Chl a and b were measured in C. Total lipids were extracted from the cells and subjected to TLC for separation into individual lipid classes, as previously described [ 7 ]. Sulfation of trehalose by Stf0 is the first committed step in SL-1 biosynthesis. A The sulfotransferase Stf0 sulfates free trehalose to initiate SL-1 biosynthesis. To assess cell envelope integrity and permeability, we challenged the bacteria with detergents or antibiotics, respectively. These data suggest that loss of the major cell envelope component SL-1 does not compromise the overall integrity or permeability of the Mtb cell envelope in vitro. Neither SL-1 nor SL-A stimulated production of TNF in any of the cell types we examined Supplementary Figure 3 , which corroborated with our microarray data to provide further evidence that purified SL-1 is not a classical pro-inflammatory stimulus. Reasons for these discrepancies with previous data could include the presence of small levels of impurities in previous SL-1 preparations, differences in the concentrations of SL-1 used, or differences in the culture conditions of mammalian cells. Figure 2 Figure 2. SL-1 induces a unique transcriptional signature in human leukocytes. SQDGs seem to be involved in the turnover of cyt f in a similar manner like D1 and raises the question of whether a similar mechanism underlies the role of SQDG in the assembly of both subunits. In cyanobacteria and plants, SQDG is synthesized in two steps.

Upon sulfate-deficiency, SQDG is almost completely degraded, whereby a major intracellular S-source for protein synthesis is ensured at an early stage, accompanied by an increase in the PG content [ 19 ].

In this study, effects of S-starvation on SQDG metabolism was investigated in freshwater microbes such as cyanobacteria, Synechococcus and Synechocystis, and a green alga, Chlorella kessleri, to gain more insight into the taxonomical distribution of SQDG degradation synthesis.

The radioactivity of SQDG was estimated relative to the total radioactivity. Meanwhile, Synechococcus disruptants during sqdB and sqdX genes, which are involved in successive reactions in the sulfolipid synthesis pathway, were respectively characterized in cellular response to sulfate-starvation.

Ceramide is synthesized from serine and palmitoyl-CoA, and sphingomyelin SM is synthesized from ceramide and phosphatidylcholine by SM synthase. Phycobilisome degradation intrinsic to Synechococcus, but not to Synechocystis, and cell growth under sulfate-starved conditions were repressed in the sqdB and sqdX disruptants, respectively, Page de presentation pour cv to in the protein type.

S-starvation caused C.

These two enzymes catalyze successive reactions, i. When needed, C. In some cases the electrostatic interactions may be very strong, as suggested by the inability of saturated SQDG molecules associated with purified chloroplast CF0-CF1 ATPase to exchange with other acidic lipids. Distinct from phosphate, sulfate, the preferred S-source for photosynthetic microbes, however shows extremely uneven distribution in aquatic habitats reviewed in [ 15 ] : although the oceans typically contain sulfate at around 29 mM, i. In order to address the role of SL-1 biosynthesis in Mtb pathogenesis, we constructed an stf0 knockout in the Erdman strain of Mtb, because it has recently been reported that the H37Rv strain can undergo spontaneous loss of the well-established virulence factor lipid phthiocerol dimycocerosate PDIM during in vitro culture. Total lipids were extracted from the cells and subjected to TLC for separation into individual lipid classes, as previously described [ 7 ]. Their distinct phenotypes, despite the common loss of the sulfolipid, inferred specific roles of sqdB and sqdX. Obtained results will be discussed from an evolutionary aspect for oxygenic photosynthetic organisms. The labeled cells were washed three times with the S-free medium, and then shifted to 32S-replete or S-free conditions for further growth.

Sulfur S is one of plants for photosynthetic organisms, similar to P, and is the essential component of proteins and sulfolipids. The distinctive feature of this substance is carbon bonded directly to sulfur as C-SO3.
