Diphthamide synthesis is linked to the eEF2‐client chaperone machinery
FEBS Letters, EarlyView.The diphthamide modification of eukaryotic translation elongation factor 2 (eEF2) is important for accurate protein synthesis. We addressed the potential coordination of de novo eEF2 synthesis with simultaneous or subsequent diphthamide modification. Our work reveals that the co‐chaperones Hgh1 and Cpr7, which are known to support folding of nascent ...

A Word-Granular Adversarial Attacks Framework for Causal Event Extraction
Entropy, 2022 As a data augmentation method, masking word is commonly used in many natural language processing tasks. However, most mask methods are based on rules and are not related to downstream tasks. In this paper, we propose a novel masking word generator, named

Techniques for Jointly Extracting Entities and Relations: A Survey [PDF]
arXiv, 2021 Relation Extraction is an important task in Information Extraction which deals with identifying semantic relations between entity mentions. Traditionally, relation extraction is carried out after entity extraction in a "pipeline" fashion, so that relation extraction only focuses on determining whether any semantic relation exists between a pair of ...

Graph Convolution for Multimodal Information Extraction from Visually Rich Documents [PDF]
North American Chapter of the Association for Computational Linguistics, 2019 Visually rich documents (VRDs) are ubiquitous in daily business and life. Examples are purchase receipts, insurance policy documents, custom declaration forms and so on.

Template design for information extraction [PDF]
Proceedings of the 5th conference on Message understanding - MUC5 '93, 1993 The design of the template for an information extraction application (or exercise) reflects the nature of the task and therefore crucially affects the success of the attempt to capture information from text. This paper addresses the template design requirement by discussing the general principles or desiderata of template design, object-oriented vs ...

Characterization of fungal carbonyl sulfide hydrolase belonging to clade D β‐carbonic anhydrase
FEBS Letters, EarlyView.Here, we performed a functional analysis of the fungal enzymes belonging to clade D of the β‐class carbonic anhydrase family (β‐D‐CA). The β‐D‐CAs in the basidiomycete Gloeophyllum trabeum and the ascomycete Trichoderma harzianum showed very low activity in the hydration of CO2 but exhibited high activity in the hydrolysis of carbonyl sulfide (COS ...

Neural Extractive Search [PDF]
arXiv, 2021 Domain experts often need to extract structured information from large corpora. We advocate for a search paradigm called ``extractive search'', in which a search query is enriched with capture-slots, to allow for such rapid extraction. Such an extractive search system can be built around syntactic structures, resulting in high-precision, low-recall ...

FEBS Letters, EarlyView.The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

Representation Learning for Information Extraction from Form-like Documents
Annual Meeting of the Association for Computational Linguistics, 2020 We propose a novel approach using representation learning for tackling the problem of extracting structured information from form-like document images.
