Abstract
Aneurinibacillus sp. H1 is a promising, moderately thermophilic, novel Gram-positive bacterium capable of the biosynthesis of polyhydroxyalkanoates (PHA) with tunable monomer composition. In particular, the strain is able to synthesize copolymers of 3-hydroxybutyrate (3HB), 4-hydroxybutyrate (4HB) and 3-hydroxyvalerate (3HV) with remarkably high 4HB and 3HV fractions. In this study we performed an in-depth material analysis of PHA polymers produced by Aneurinibacillus sp. H1 in order to describe how the monomer composition affects fundamental structural and physicochemical parameters of the materials in the form of solvent-casted films. Results of infrared spectroscopy, X-ray diffractometry and thermal analysis clearly show that controlling the monomer composition enables optimization of PHA crystallinity both qualitatively (the type of the crystalline lattice) and quantitatively (the overall degree of crystallinity). Furthermore, resistance of the films against thermal and/or enzymatic degradation can also be manipulated by the monomer composition. Results of this study hence confirm Aneurinibacillus sp. H1 as an auspicious candidate for thermophilic production of PHA polymers with material properties that can be tuned together with their chemical composition by the corresponding adjustment of the cultivation process.

Polyester modification of the mammalian TRPM8 channel protein: implications for structure and function. Cell Rep 2013; 4:302-315. [PMID: 23850286 DOI: 10.1016/j.celrep.2013.06.022] [Citation(s) in RCA: 41] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2013] [Revised: 04/01/2013] [Accepted: 06/18/2013] [Indexed: 12/18/2022] Open
Abstract
The TRPM8 ion channel is expressed in sensory neurons and is responsible for sensing environmental cues, such as cold temperatures and chemical compounds, including menthol and icilin. The channel functional activity is regulated by various physical and chemical factors and is likely to be preconditioned by its molecular composition. Our studies indicate that the TRPM8 channel forms a structural-functional complex with the polyester poly-(R)-3-hydroxybutyrate (PHB). We identified by mass spectrometry a number of PHB-modified peptides in the N terminus of the TRPM8 protein and in its extracellular S3-S4 linker. Removal of PHB by enzymatic hydrolysis and site-directed mutagenesis of both the serine residues that serve as covalent anchors for PHB and adjacent hydrophobic residues that interact with the methyl groups of the polymer resulted in significant inhibition of TRPM8 channel activity. We conclude that the TRPM8 channel undergoes posttranslational modification by PHB and that this modification is required for its normal function.

Abstract
Poly-3-hydroxybutyrate (PHB) is a biological polyester present in bacteria and eukaryotic cells. Long-chain (or storage) sPHB (up to 100,000 residues) is typically present in PHB-accumulating bacteria and localized in specialized granules known as carbonosomes. In these organisms, sPHB plays a major role as carbon and energy storage. On the other hand, short-chain (or complexed) cPHB (10-100 residues) is present in eukaryotic organisms, including mammals as well as in many bacteria. Previous studies indicated that cPHB is localized in various subcellular compartments of the eukaryotic organisms. Here, we used fluorescent microscopy to directly investigate the localization of PHB in mammalian cells. PHB was visualized in cultured U87 cells using fluorescent probe BODIPY 493/503. Specificity of PHB staining was confirmed by markedly decreased fluorescence of samples treated with PHB-specific depolymerase (PhaZ7). We found that PHB is associated with granules, and that these PHB-enriched granules do not co-localized with mitochondria, lysosomes, or endoplasmic reticulum. These results suggest that, in mammalian cells, PHB can accumulate in the cytoplasm in granules similar to 'energy storage' carbonosomes found in PHB-accumulating bacteria.
