Transcriptome analysis revealed the function of five tandemly duplicated nAChRs in the transplantation immunity in pearl oyster Pinctada fucata martensii.

nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels that play an important role in the homeostatic regulation of physiological functions. Our previous studies showed that nAChRs in the genome of pearl oyster Pinctada fucata martensii (PmnAChRs) were expanded through tandem duplication. This study aimed to analyze the function of five tandemly duplicated PmnAChRs in the transplantation immunity in P.

miR-10a-3p Participates in Nacre Formation in the Pearl Oyster Pinctada fucata martensii by Targeting NPY.

MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression via the recognition of their target messenger RNAs. MiR-10a-3p plays an important role in the process of ossification. In this study, we obtained the precursor sequence of miR-10a-3p in the pearl oyster Pinctada fucata martensii (Pm-miR-10a-3p) and verified its sequence by miR-RACE technology, and detected its expression level in the mantle tissues of the pearl oyster P.

Structure and function of the lanthanide-dependent methanol dehydrogenase XoxF from the methanotroph Methylomicrobium buryatense 5GB1C.

In methylotrophic bacteria, which use one-carbon (C1) compounds as a carbon source, methanol is oxidized by pyrroloquinoline quinone (PQQ)-dependent methanol dehydrogenase (MDH) enzymes. Methylotrophic genomes generally encode two distinct MDHs, MxaF and XoxF. MxaF is a well-studied, calcium-dependent heterotetrameric enzyme whereas XoxF is a lanthanide-dependent homodimer.

From micelles to bicelles: Effect of the membrane on particulate methane monooxygenase activity.

Particulate methane monooxygenase (pMMO) is a copper-dependent integral membrane metalloenzyme that converts methane to methanol in methanotrophic bacteria. Studies of isolated pMMO have been hindered by loss of enzymatic activity upon its removal from the native membrane. To characterize pMMO in a membrane-like environment, we reconstituted pMMOs from () (Bath) and () 20Z into bicelles.

Mantle Branch-Specific RNA Sequences of Moon Scallop Amusium pleuronectes to Identify Shell Color-Associated Genes.

Amusium pleuronectes (Linnaeus) that secretes red- and white-colored valves in two branches of mantle tissues is an excellent model for shell color research. High-throughput transcriptome sequencing and profiling were applied in this project to reveal the detailed molecular mechanism of this phenotype differentiation. In this study, 50,796,780 and 54,361,178 clean reads were generated from the left branch (secreting red valve, RS) and right branch (secreting white valve, WS) using the Illumina Hiseq 2000 platform.
