Characterization of Actinoplanes missouriensis Spore Flagella. [PDF]

Applied and Environmental Microbiology, 2011
ABSTRACT Actinoplanes missouriensis spores swim with a tuft of flagella. Flagella of newborn spores are wrapped with a membranous sheath. When the sheath is unwrapped, spores start swimming. Flagellar length is kept short, at around 1.9 μm, which covers half the circumference of the spore.

Multimodal Molecular Imaging Reveals a Novel Membrane Component in Sporangia of the Rare Actinomycete Actinoplanes missouriensis [PDF]

ACS Omega
The bacterium Actinoplanes missouriensis belongs to the genus Actinoplanes, a prolific source of useful natural products. This microbe forms globular structures called sporangia, which contain many dormant spores. Recent studies using transmission electron microscopy have shown that the A.

Involvement of BldC in the Formation of Physiologically Mature Sporangium in Actinoplanes missouriensis. [PDF]

J Bacteriol, 2022
BldC is a global transcriptional regulator that acts as a “brake” in the morphological differentiation of Streptomyces . BldC-like proteins are widely distributed throughout eubacteria, but their orthologs have not been studied outside streptomycetes.

Characterization of Zoospore Type IV Pili in Actinoplanes missouriensis. [PDF]

J Bacteriol, 2019
Bacterial zoospores are interesting cells in that their physiological state changes dynamically: they are dormant in sporangia, show temporary mobility after awakening, and finally stop swimming to germinate in niches for vegetative growth. However, the cellular biology of a zoospore remains largely unknown.

Preparation of Actinoplanes missouriensis Zoospores and Assay for Their Adherence to Solid Surfaces. [PDF]

Bio Protoc, 2019
Spherical zoospores of a rare actinomycete, Actinoplanes missouriensis, adhere to various hydrophobic solid surfaces by means of type IV pili. The purpose of this protocol is to provide detailed descriptions of the preparation of A. missouriensis zoospores and an assay for the adhesion of the zoospores to solid surfaces.

Genetic and Transcriptional Analyses of the Flagellar Gene Cluster in Actinoplanes missouriensis. [PDF]

J Bacteriol, 2016
ABSTRACT Actinoplanes missouriensis , a Gram-positive and soil-inhabiting bacterium, is a member of the rare actinomycetes. The filamentous cells produce sporangia, which contain hundreds of flagellated spores that can swim rapidly for a short period of time until they find niches for ...

Regulation of Sporangium Formation by BldD in the Rare Actinomycete Actinoplanes missouriensis. [PDF]

J Bacteriol, 2017
ABSTRACT The rare actinomycete Actinoplanes missouriensis forms sporangia, including hundreds of flagellated spores that start swimming as zoospores after their release. Under conditions suitable for vegetative growth, zoospores stop swimming and germinate. A comparative proteome analysis between zoospores

Identification and Characterization of a Cell Wall Hydrolase for Sporangiospore Maturation in Actinoplanes missouriensis. [PDF]

J Bacteriol, 2019
In streptomycetes, an aerial hypha is compartmentalized by multiple septations into prespores, which become spores through a series of maturation processes. However, little is known about these maturation processes. The rare actinomycete Actinoplanes missouriensis produces sporangiospores, which are assumed to be ...

Complete genome sequence of the motile actinomycete Actinoplanes missouriensis 431(T) (= NBRC 102363(T)). [PDF]

Stand Genomic Sci, 2012
Actinoplanes missouriensis Couch 1963 is a well-characterized member of the genus Actinoplanes, which is of morphological interest because its members typically produce sporangia containing motile spores. The sporangiospores are motile by means of flagella and exhibit chemotactic properties.

A Novel Glucose Isomerase from Caldicellulosiruptor bescii with Great Potentials in the Production of High‐Fructose Corn Syrup

BioMed Research International, Volume 2020, Issue 1, 2020., 2020
Glucose isomerase (GI) that catalyzes the conversion of D‐glucose to D‐fructose is one of the most important industrial enzymes for the production of high‐fructose corn syrup (HFCS). In this study, a novel GI (CbGI) was cloned from Caldicellulosiruptor bescii and expressed in Escherichia coli.
