The Problem of the "Prebiotic and Never Born Proteins"

, 2012
It has been argued that the limited set of proteins used by life as we know it could not have arisen by the process of Darwinian selection from all possible proteins.

Characterisation of a phylogenetically distinct PL25 family ulvan lyase from a seaweed biomass enriched metagenome

The FEBS Journal, EarlyView.
Ulvan is a polysaccharide available from green seaweed with beneficial properties for various applications. The full potential of ulvan requires enzymatic degradation of the polymer, thus producing ulvan oligosaccharides. This study expands the armoury of characterised ulvan lyases.

CO2‐sensitive K+ channel traffic affects stomata and whole‐plant water use

Journal of Integrative Plant Biology, EarlyView.
CO2‐responsive regulation of membrane trafficking influences the density of the potassium ion (K+) channel KAT1 at the plasma membrane. CO2‐sensitive traffic, dependent on trafficking by the SNARE SYP121, impacts stomatal gas exchange and plant growth.

Purification, Characterization, cDNA Cloning, and Bioinformatic Analysis of Zinc-Binding Protein from Magallana hongkongensis

Molecules
Oysters contain significant amounts of the zinc element, which may also be found in their proteins. In this study, a novel zinc-binding protein was purified from the mantle of the oyster Magallana hongkongensis using two kinds of gel filtration ...

Irreversible thermal denaturation of human carbonic anhydrase [PDF]

Carbonic Anhydrase (CA; carbonate hydro-lyase, EC 4.2.1.1)), a zinc containing enzyme, catalyzes reversible hydration of carbon dioxide. This metalloenzyme is found in animals, photosynthesizing organisms, and in some nonphotosynthetic bacteria. Thermal

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

New Phytologist, EarlyView.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...

Photosynthetic primary production in the Mesoproterozoic

New Phytologist, EarlyView.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Vision outcomes in dogs with primary glaucoma surgically treated with lensectomy and endolaser cyclophotocoagulation after an Ahmed valve gonioimplantation failure

Veterinary Ophthalmology, Volume 28, Issue 2, Page 207-217, March 2025.
Abstract Objective The aim of this study was to retrospectively evaluate vision outcomes of dogs with primary angle closure glaucoma (PACG) that underwent Ahmed valve gonioimplantation (AVG) followed by lensectomy and endolaser cyclophotocoagulation (ECP) with or without bleb resection after AVG failure.
