AbstractAbstract
It was reported that LAMMER kinase in Schizosaccharomyces pombe plays an important role in cation-dependent and galactose-specific flocculation. Analogous to other flocculating yeasts, when cell wall extracts of the Δlkh1 strain were treated to the wild-type strain, it displayed flocculation. Gas2, a 1,3-β-glucanosyl transferase, was isolated from the EDTA-extracted cell-surface proteins in the Δlkh1 strain. While disruption of the gas2+ gene was not lethal and reduced the flocculation activity of the Δlkh1 strain, the expression of a secreted form of Gas2, in which the GPI anchor addition sequences had been removed, conferred the ability to flocculate upon the WT strain. The Gas2-mediated flocculation was strongly inhibited by galactose but not by glucose. Immunostaining analysis showed that the cell surface localization of Gas2 was crucial for the flocculation of fission yeast. In addition, we identified the regulation of mbx2+ expression by Lkh1 using RT-qPCR. Taken together, we found that Lkh1 induces asexual flocculation by regulating not only the localization of Gas2 but also the transcription of gas2+ through Mbx2.

AbstractAbstract
Gel-free shotgun phosphoproteomics of unicellular cyanobacterium Synechocystis sp. PCC 6803 has not been reported up to now. The purpose of this study is to develop directed membrane phosphoproteomic method in Synechocystis sp. Total Synechocystis membrane proteins were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and phosphoprotein-stained gel bands were selectively subjected to in-gel trypsin digestion. The phosphorylation sites of the resulting peptides were determined by assigning the neutral loss of [M-H3PO4] to Ser, Thr, and Tyr residues using nano-liquid chromatography 7 Tesla Fourier transform mass spectrometry. As an initial application, 111 proteins and 33 phosphoproteins were identified containing 11 integral membrane proteins. Identified four unknown phosphoproteins with transmembrane helices were suggested to be involved in membrane migration or transporters based on BLASTP search annotations. The overall distribution of hydrophobic amino acids in pTyr was lower in frequency than that of pSer or pThr. Positively charged amino acids were abundantly revealed in the surrounding amino acids centered on pTyr. A directed shotgun membrane phosphoproteomic strategy provided insight into understanding the fundamental regulatory processes underlying Ser, Thr, and Tyr phosphorylation in multi-layered membranous cyanobacteria.

AbstractAbstract
Two novel calcium-binding proteins, named CAB-I and CAB-II, have been isolated from Streptomyces coelicolor. Purification of the calcium-binding proteins involved heat treatment, fractionation with ammonium sulfate, acid treatment, anion exchange and hydrophobic interaction column chromatography, FPLC gel filtration, and preparative isoelectric focusing. A chelex competitive assay and ^45Ca autoradiography verified the calcium-binding ability of the proteins. The major band CAB-II has an apparent molecular weight of 26,000 determined by SDS-polyacrylamide gel electrophoresis and 340,000 determined by gel filtration. The isoelectric point of this molecule showed the acidic nature of the molecule. N-terminal amino acid sequence analysis shows homology to rat Ca^2+/calmodulin-dependent protein kinase-II (CAB-II) and yeast phosphoprotein phosphatase (CAB-I).
