H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

The FEBS Journal, EarlyView.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Toward understanding the catalytic mechanism for two classes of bacterial phospholipid N‐methyltransferases

The FEBS Journal, EarlyView.
Phospholipid N‐methyltransferases (Pmts) synthesize phosphatidylcholine in many bacteria. In this study, we compared the catalytic mechanisms of two bacterial Pmt classes: the Rhodobacter (R‐) and the Sinorhizobium (S‐) type. Representative enzymes for each class were derived from Rubellimicrobium thermophilum and Agrobacterium tumefaciens ...

Coniferyl aldehyde from the phenylpropanoid pathway targets pyruvate kinase in Dactylobotrys graminicola to confer sheath rot resistance in hulless barley

Journal of Integrative Plant Biology, EarlyView.
Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...

Roles of PknB and CslA in Cell Wall Morphogenesis of Streptomyces

Molecular Microbiology, EarlyView.
Streptomyces grow by extending hyphal tips, a process regulated by polarisome complexes anchored by DivIVA. Using a genetic screen based on toxic DivIVA overproduction, we identified the kinase PknB as a key regulator of cell envelope construction.

Staurosporine Targets Mitochondrial Regulator VdAtuA3 to Disrupt Mitochondrial Homeostasis to Control Verticillium Wilt

Plant Biotechnology Journal, EarlyView.
ABSTRACT Mitochondria serve as cellular powerhouses that generate ATP via electron transport chain complexes and orchestrate metabolism‐apoptosis cross‐talk, yet genes maintaining mitochondrial homeostasis remain underexplored as antifungal targets. In this study, a previously uncharacterised protein VdAtuA3 was identified as a novel interactor with ...

Microbial Strategies for the Degradation of Spent Lubricating Oil: A Comparative Study of Isolate Bacterium and Consortium Cultures

Water and Environment Journal, EarlyView.
This show the biodegradation of spent lubricating oil by Bacillus sp. and a marine bacterial consortium. The consortium showed higher growth, biosurfactant production and oil removal efficiency than the isolated strain, highlighting its potential for bioremediation ABSTRACT Spent automotive lubricating oil contains complex hydrocarbons and heavy metals,
