Biodegradació de nous materials segons la norma 14855
, 2018 Des del seu origen a la primera meitat del segle XX, els plàstics han anat prenent cada cop més protagonisme a les nostres vides, generant en conseqüència cada cop més quantitat de residus plàstics arreu del món. Una de les principals problemàtiques que aquests presenten és la seva incapacitat de degradar-se, fet que provoca la seva acumulació a ...

Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Architecture and materials selection in multi-materials design [PDF]
, 2014 The design process involving both the architecture and the materials represents an hard task mainly due to the high number of potential configurations, thus requiring firstly the development of new and more rigorous approaches but also the development of

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Els agresomes, nou material biofuncional en nanomedicina i biotecnologia
, 2015 Los cuerpos de inclusión bacterianos son materiales proteicos nanoestructurados con aplicaciones biomédicas como la entrega de fármacos o las topografías biofuncionales. Sin embargo, muchas enzimas con posibles aplicaciones biomédicas o industriales no pueden ser producidas en sistemas bacterianos.

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
