Significance Aquatic organisms are rarely found in amber, but when they occur provide invaluable evidence for the better understanding of amber taphonomy and past ecosystems. We report an ammonite several marine gastropods alongside a mixed assemblage intertidal terrestrial forest floor mid-Cretaceous Burmese amber. Our discovery indicates that was living near dynamic shifting coastal environment. The also provides supporting age which is still debated, represents rare example dating using...
The Zhangpu biota provides a new insight into biodiversity redistribution during the Mid-Miocene Climatic Optimum.
Pseudelzalia longiseta gen. nov, sp. nov. and Paramonohystera sinica from subtidal sediment in the East China Sea are described. is characterized by 6 labial papillae 10 cephalic setae, cylindrical buccal cavity, elongate (>2 anal body diameter) spicules, conico-cylindrical tail devoid of terminal setae. It differs Elzalia absence 647–853 μm long, has 7–8 long cervical 11–14 caudal 25–41 spicules about 2.1–2.7 diameter, pointed tail-tip. possesses 12 a character found four congeners:...
Biosynthesis of angucyclines: We characterized an accessory enzyme, JadH as a FAD and NAD(P)H-dependent bifunctional hydroxylase/dehydrase involved in jadomycin biosynthesis by identifying its real product. Homologues have been found all cloned angucycline biosynthetic clusters were proposed to similar functions JadH.
Phytase supplied in feeds for monogastric animals is important improving nutrient uptake and reducing phosphorous pollution. High-thermostability phytases are particularly desirable due to their ability withstand transient high temperatures during feed pelleting procedures. A comparison of crystal structures the widely used industrial Aspergillus niger PhyA phytase (AnP) with its close homolog, thermostable fumigatus (AfP), suggests 18 residues three segments associated thermostability. In...
Abstract Burmese amber continues to provide unique insights into the terrestrial biota inhabiting tropical equatorial forests during mid-Cretaceous time. In contrast large amount and great diversity of species retrieved so far, aquatic constitute rare inclusions. Here we describe first freshwater snail ever preserved in amber. The new Galba prima sp. nov. belongs family Lymnaeidae, today a diverse near globally distributed family. Its inclusion is probably result amphibious lifestyle typical...
Deacetylation of 7-aminocephalosporanic acid (7-ACA) at position C-3 provides valuable starting material for producing semisynthetic β-lactam antibiotics. However, few enzymes have been characterized in this process before now. Comparative analysis the genome thermophilic bacterium Alicyclobacillus tengchongensis revealed a hypothetical protein (EstD1) with typical esterase features. The EstD1 was functionally cloned, expressed, and purified from Escherichia coli BL21(DE3). It indeed...
Abstract Background Clostridium thermocellum is a Gram-positive thermophilic anaerobic bacterium with the unusual capacity to convert cellulosic biomass into ethanol and hydrogen. Identification characterization of protein complexes in C. are important toward understanding its metabolism physiology. Results A two dimensional blue native/SDS-PAGE procedure was developed separate membrane . Proteins spots were identified by MALDI-TOF/TOF Mass spectrometry. 24 proteins representing 13 distinct...
Abstract Computed tomographic (CT) imaging allows new accessibility to shells of gastropod fossil taxa and their extant relatives, providing data for interpreting former systematic assignments. The highly questionable ellobiid assignment the nonmarine genus Protocarychium Pan, 1982 from Lower Jurassic Hunan, China, is reevaluated using CT assess internal aspects shell. By comparing these those stylommatophoran, ellobiid, caenogastropod clades in literature, this work reveals that bears no...
When seldom life history events serendipitously get documented by exceptional preservation in the fossil record, a unique telescopic opportunity arises for interpreting fossils within their paleoenvironment as well understanding ancestral relationships of current forms. We present rare glimpse live birth terrestrial mother snail, incidentally, engulfed amber she released her young tropical forest during mid-Cretaceous (early Cenomanian). The finding featuring snail's 99-million-year-old...
Abstract Non-marine gastropod fossils are abundant in the Middle Jurassic Toutunhe Formation Ziniquanzi section of southern Junggar Basin, Xinjiang, NW China, and Lower Sangonghe Tuziakeneigou Karamay northwestern Basin. Nine species attributed to families Viviparidae, Valvatidae Hydrobiidae one undetermined Truncatelloidea systematically re-described. Most these widely distributed China can be used for biostratigraphic correlation. The palaeoenvironment was reconstructed by using available...
Rapid identification of glycosylation sites glycoproteins is urgently needed in the study glycoproteomics. In present work, a rapid and simple method based on non-specific digestion gel-separated matrix-assisted laser desorption/ionization tandem time-of-flight mass spectrometry was described, which can efficiently identify N-linked sites. One-step in-gel ribonuclease B (RNase B) by proteinase K employed to generate glycopeptides with short discrepant peptide composition. When compared...
Two new species of free-living marine nematodes, Litinium dispariseta sp. nov. and Wieseria minor are described from an abyssal plain with a water depth 4117–5035 m near the Southern Kyushu-Palau Ridge in tropical Western Pacific Ocean. is characterized by having distinct inner labial setae two times longer than outer setae, wrench-like amphideal foveas, single preanal midventral supplementary seta short cylindrical tail bluntly rounded tip. It differs congeners its distinctly long relative...
This study reports an oven-controlled microelectromechanical systems oscillator with integrated micro-evaporation trimming that achieves frequency stability over the industrial temperature range and permanent after vacuum packaging. The length-extensional-mode resonator is micro-oven controlled doped degenerately phosphorous to achieve a instability of ±2.6 parts per million (ppm) in −40 85 °C. micro-evaporators are bonded resonator, face-to-face, encapsulated vacuum. During trimming, heated...
