The microorganisms that evolved at low temperatures express cold-adapted enzymes
endowed with unique catalytic properties in comparison to their mesophilic homologues, ie …

Solar radiation represents a key abiotic factor in the evolution of life in the oceans. In
general, marine, biota—particularly in euphotic and dysphotic zones—depends directly or …

We present an update of the 'key points' from the Antarctic Climate Change and the
Environment (ACCE) report that was published by the Scientific Committee on Antarctic …

Marine organisms have developed a series of defense and adaptation strategies, permitting
them to live and survive in peculiar environments, ranging from temperate to tropical and …

The application of an ever-increasing number of methodological approaches and tools is
positively contributing to the development and yield of bioprospecting procedures. In this …

If life without heme-Fe were at all possible, it would definitely be different. Indeed this
complex and versatile iron-porphyrin macrocycle upon binding to different “globins” yields …

Antarctica is an untapped reservoir of bacterial communities, which are able to adapt to a
huge variety of strategies to cope with extreme conditions and, therefore, are capable of …

A new γ-class carbonic anhydrase (CA, EC 4.2. 1.1) was cloned, purified and characterized
from the Antarctic bacterium Pseudoalteromonas haloplanktis, PhaCAγ. The enzyme has a …

Truncated hemoglobins build one of the three branches of the globin protein superfamily.
They display a characteristic two‐on‐two α‐helical sandwich fold and are clustered into …

Genomic and proteomic advances in extremophile microorganism studies are increasingly
demonstrating their ability to produce a variety of enzymes capable of converting biomass …
