The NADH:quinone oxidoreductase (complex I) has evolved from a combination of smaller functional building blocks. Chloroplasts and cyanobacteria contain a complex I-like enzyme having only 11 subunits. This enzyme lacks the N-module which h...
Characterization and evolution of MHC class II B genes in Ardeid birds [0.03%]
鹭科鸟类MHC II B基因的特征及演化分析
Li Li,Xiaopin Zhou,Xiaolin Chen

Major histocompatibility complex (MHC) is a multi-gene family that is very suitable to investigate a wide range of open questions in evolutionary ecology. In this study, we characterized two expressed MHC class II B genes (DAB1 and DAB2) in...
Compositional and structural features related to thermal stability in the archaea SRP19 and SRP54 signal recognition particle proteins [0.03%]

To survive at high temperature, thermophile organisms must adapt their biomolecules. In both nucleic acids and proteins, this adaptation involves a vast array of compositional and structural modifications. The archaea stand out as the only ...
Evolutionary dynamics of the mS952 intron: a novel mitochondrial group II intron encoding a LAGLIDADG homing endonuclease gene [0.03%]
mS952内含子的进化动力学：一个新的线粒体第II组内含子编码LAGLIDADG同源酶原基因

Examination of the mitochondrial small subunit ribosomal RNA (rns) gene of five species of the fungal genus Leptographium revealed that the gene has been invaded at least once at position 952 by a group II intron encoding a LAGLIDADG homing...
Phylogenetic distribution and evolutionary history of bacterial DEAD-Box proteins [0.03%]
细菌DEAD盒蛋白的谱系分布及进化历史
Varinia López-Ramírez,Luis D Alcaraz,Gabriel Moreno-Hagelsieb et al.
Varinia López-Ramírez et al.
DEAD-box proteins are found in all domains of life and participate in almost all cellular processes that involve RNA. The presence of DEAD and Helicase_C conserved domains distinguish these proteins. DEAD-box proteins exhibit RNA-dependent ...
Novel hydrophobins from Trichoderma define a new hydrophobin subclass: protein properties, evolution, regulation and processing [0.03%]
从绿僵菌鉴定出一种新的羟基磷灰石亚类：蛋白质特性、进化、调节和处理
Verena Seidl-Seiboth,Sabine Gruber,Ugur Sezerman et al.
Verena Seidl-Seiboth et al.
Hydrophobins are small proteins, characterised by the presence of eight positionally conserved cysteine residues, and are present in all filamentous asco- and basidiomycetes. They are found on the outer surfaces of cell walls of hyphae and ...
RrS1-like sequences of water frogs from Central Europe and around the Aegean Sea: chromosomal organization, evolution, possible function [0.03%]
中央欧洲和爱琴海周围水域蛙类中的RrS1_like序列：染色体组织、进化及可能功能
Silvia Marracci,Valentina Michelotti,Gaston-Denis Guex et al.
Silvia Marracci et al.
RrS1-like sequences of water frogs (genus Pelophylax) display varied genomic organization, whereas the centromeric hybridization pattern reveals species-specific differences. Using fluorescent in situ hybridization, Pelophylax cf. bedriagae...
The presence in tRNA molecule sequences of the double hairpin, an evolutionary stage through which the origin of this molecule is thought to have passed [0.03%]
tRNA分子序列中的双发卡结构的存在，这种结构被认为是在该分子进化的某个阶段中存在的结构
Sergio Branciamore,Massimo Di Giulio
Sergio Branciamore
We analyse 6,810 tRNAs, calculating the free energy of the corresponding double hairpin and 'cigar' secondary structures, for which we find a high thermodynamic and statistical significance. We also analyse these tRNAs for similarity and co...

Joël Gaffé et al.
Insertion sequence (IS) elements are present in almost all bacterial genomes and are mobile enough to provide genomic tools to differentiate closely related isolates. They can be used to estimate genetic diversity and identify fitness-enhan...
Deconstructing a complex molecular phenotype: population-level variation in individual venom proteins in Eastern Massasauga Rattlesnakes (Sistrurus c. catenatus) [0.03%]
