Microcin C51 Plasmid Genes: Possible Source of Horizontal Gene Transfer [PDF]
Antimicrobial Agents and Chemotherapy, 2003 ABSTRACT Microcin C51 (MccC51) is an antimicrobial nucleotide-heptapeptide produced by a natural Escherichia coli strain. A 5.7-kb fragment of the pC51 plasmid carrying the genes involved in MccC51 production, secretion, and self-immunity was sequenced, and the genes were characterized. The sequence of the

Synthesis of the C50 diastereomers of the C33–C51 fragment of stambomycin D
Organic Chemistry Frontiers, 2022 The preparation of two C50 diastereomers of the C33–C51 region of stambomycin D is described. In addition to excellent correlation with the natural product, this synthesis establishes conditions for eventual global deprotection.

Structure of microcin C51, a new antibiotic with a broad spectrum of activity
FEBS Letters, 1995 The structure of microcin C51, a new antibiotic produced by E. coli, has been determined. This antibiotic was shown to be a 1.18 kDa nucleotide peptide. It consists of a heptapeptide with formylmethionine as the N‐terminus and a C‐terminal asparagine linked with nebularin‐5′‐monophosphate through the three‐methylene bridge. The OH‐group of threonine is

BRCA1-A and BRISC: Multifunctional Molecular Machines for Ubiquitin Signaling
Biomolecules, 2020 The K63-linkage specific deubiquitinase BRCC36 forms the core of two multi-subunit deubiquitination complexes: BRCA1-A and BRISC. BRCA1-A is recruited to DNA repair foci, edits ubiquitin signals on chromatin, and sequesters BRCA1 away from the site of ...

An EOQ model for multiple products with varying degrees of substitutability
Economics: Journal Articles, 2019 In this paper, the authors present an EOQ model with substitutions between products and a dynamic inventory replenishment policy. Their key assumption is that many products in the market are substitutable at different levels, and that, in most cases, a ...

Joint Optimization Via Deep Reinforcement Learning in Wireless Networked Controlled Systems
IEEE Access, 2022 This paper proposes a deep Reinforcement Learning (RL) based co-design approach for joint-optimization of wireless networked control systems (WNCS) where the co-design approach can help achieve optimal control performance under network uncertainties, e.g.
