Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

open access: yesThe FEBS Journal, EarlyView.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

Investigating transthyretin variants H88R and I107V in amyloid priming: From destabilization to complete dissociation

open access: yesThe FEBS Journal, EarlyView.
Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

Mechanistic insights into HapC: A key enzyme in prodiginine biosynthesis in Hahella chejuensis

open access: yesThe FEBS Journal, EarlyView.
HapC catalyzes prodiginine biosynthesis through coordinated movements of its ATP‐binding, substrate‐binding, and catalytic‐swivel domains. The enzyme shows tolerance toward short‐chain MAP analogs, and docking analyses reveal key residues and structural features underlying its substrate flexibility.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

open access: yesThe FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Local Angler Knowledge Reveals Declines in Fishing Quality for Black Bass in Lakes of Eastern Ontario

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Local ecological knowledge can be useful to assess data‐limited fisheries such as the Ontario Black Bass (Micropterus spp.) recreational fishery. We surveyed local anglers using the Life History Calendar approach to determine if there were perceived changes in fishing quality for Black Bass in eastern Ontario across different time periods. For

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

Impact of Environmental Conditions on the Spawning Migration of Sea Trout (Salmo trutta L.) in Two Large, Sub‐Arctic River Systems

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...

Lake Michigan Salmonid Stocking Costs in Wisconsin [PDF]

open access: yes
The costs of stocking salmonids in the Wisconsin waters of Lake Michigan are estimated for 1985. Estimation procedures and costs per stocked and captured fish are presented. Fingerlings of a species were found in most cases to cost more per captured fish
