TL;DR: This is the first report of naturally occurring biliproteins carrying either 15,16-dihydrobiliverdin or mesobiliverdin chromophores, and the identity of the bilin prosthetic groups on cryptophycean phycobiliprotein cannot be unambiguously inferred from simple inspection of the visible absorption spectra.

TL;DR: Fluorescent cyanine heterodimers that exploit resonance energy transfer to achieve strong emission above 650 nm with 488-nm excitation and the quenching of donor fluorescence are designed, synthesized, and characterized.

TL;DR: It was found that papaya lysozyme has a molecular weight of about 25,000 and that glycine is its sole amino-terminal residue, and molecular weight determinations in dissociating solvents indicate that the molecule consists of a single polypeptide chain.

TL;DR: Electron microscopy showed the three types of phycobilisomes to have a hemi-disc appearance, although their detailed structures were quite different, as well as independent of the detergent used during the preparation.
Abstract: Properties of cyanobacterial phycobilisomes (from Synechococcus spp. 6301 and 6312 and Synechocystis sp. 6701) prepared in the presence of two different zwitterionic detergents were compared to those of phycobilisomes detached from membranes with the nonionic detergent Triton X-100 and then freed from Triton by sedimentation through high-salt sucrose density gradients. The absorption spectra, polypeptide composition, and ultrastructure of phycobilisomes were independent of the detergent used during the preparation. Phycobilisomes from certain cyanobacteria aggregated in the absence of detergent. Such aggregation was not seen in preparations containing zwitterionic detergents. Aggregation of phycobilisomes led to a partial quenching of their fluorescence. Electron microscopy showed the three types of phycobilisomes to have a hemi-disc appearance, although their detailed structures were quite different.

TL;DR: A novel post-translationally modified residue, gamma-N-methylasparagine, was detected in the beta subunit of Anabaena variabilis allophycocyanin, the first report of gamma- N-methyl asparagine in a protein.

TL;DR: The results of an international collaboration to produce and make freely available a draft sequence of the human genome are reported and an initial analysis is presented, describing some of the insights that can be gleaned from the sequence.
Abstract: The human genome holds an extraordinary trove of information about human development, physiology, medicine and evolution. Here we report the results of an international collaboration to produce and make freely available a draft sequence of the human genome. We also present an initial analysis of the data, describing some of the insights that can be gleaned from the sequence.

TL;DR: PfPMP1)与感染红细胞、树突状组胞以及胎盘的单个或多个受体作用,在黏附及免疫逃避中起关键的作�ly.
Abstract: 抗原变异可使得多种致病微生物易于逃避宿主免疫应答。表达在感染红细胞表面的恶性疟原虫红细胞表面蛋白1(PfPMP1)与感染红细胞、内皮细胞、树突状细胞以及胎盘的单个或多个受体作用,在黏附及免疫逃避中起关键的作用。每个单倍体基因组var基因家族编码约60种成员,通过启动转录不同的var基因变异体为抗原变异提供了分子基础。

TL;DR: Semiconductor nanocrystals prepared for use as fluorescent probes in biological staining and diagnostics have a narrow, tunable, symmetric emission spectrum and are photochemically stable.
Abstract: Semiconductor nanocrystals were prepared for use as fluorescent probes in biological staining and diagnostics. Compared with conventional fluorophores, the nanocrystals have a narrow, tunable, symmetric emission spectrum and are photochemically stable. The advantages of the broad, continuous excitation spectrum were demonstrated in a dual-emission, single-excitation labeling experiment on mouse fibroblasts. These nanocrystal probes are thus complementary and in some cases may be superior to existing fluorophores.

TL;DR: Highly luminescent semiconductor quantum dots (zinc sulfide-capped cadmium selenide) have been covalently coupled to biomolecules for use in ultrasensitive biological detection and these nanometer-sized conjugates are water-soluble and biocompatible.
Abstract: Highly luminescent semiconductor quantum dots (zinc sulfide-capped cadmium selenide) have been covalently coupled to biomolecules for use in ultrasensitive biological detection. In comparison with organic dyes such as rhodamine, this class of luminescent labels is 20 times as bright, 100 times as stable against photobleaching, and one-third as wide in spectral linewidth. These nanometer-sized conjugates are water-soluble and biocompatible. Quantum dots that were labeled with the protein transferrin underwent receptor-mediated endocytosis in cultured HeLa cells, and those dots that were labeled with immunomolecules recognized specific antibodies or antigens.
