Defining the SOS operon of coliphage 186
, 1996 We have sequenced the LexA-controlled operon of coliphage 186 that carries the tum gene, whose product is necessary for UV induction of the 186 prophage. The operon consists of orf95 and orf97, and we have identified orf95 as the tum gene.

British Journal of Pharmacology, EarlyView.Background and Purpose Degeneration of the pontine noradrenergic and midbrain dopaminergic systems contributes to cognitive‐behavioural disturbances during the prodromal stages of Alzheimer's disease (AD). We developed a genetically engineered, programmable probiotic Escherichia coli Nissle 1917 strain (EcNrhaL‐DOPA) capable of producing L‐3,4 ...

A quantitative study of the lac operon
, 2005 The lac operon has been key in the study of genetic regulation. Consisting of three structural genes and a regulatory domain, the lac operon controls the manufacture of lactose-digesting enzymes in E. coli bacteria.

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea
The FEBS Journal, EarlyView.S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

A comprehensive study on ferredoxin isoforms in the cyanobacterium Synechocystis sp. PCC 6803
The FEBS Journal, EarlyView.Ferredoxins are small FeS cluster‐containing proteins that play a central role in distributing electrons within the cell. The cyanobacterium Synechocystis sp. PCC 6803 contains several ferredoxin isoforms and their biophysical properties (UV/Vis and EPR spectra, Em potential), expression patterns, and interactions with the electron donors photosystem I

Catalysis and allostery in bacterial ATP phosphoribosyltransferases
The FEBS Journal, EarlyView.ATP phosphoribosyltransferase (ATPPRT) catalyses the first reaction of L‐histidine biosynthesis. L‐Histidine allosterically inhibits ATPPRT to regulate this energy‐intensive pathway in histidine‐synthesising organisms, such as bacteria, archaea and plants.

FucR Functions as a Transcriptional Regulator for L-Fucose Utilization in Campylobacter jejuni
MicroorganismsCampylobacter jejuni is an enteric pathogen and a major cause of foodborne illness worldwide. It has been shown that C. jejuni primarily utilizes amino acids as its preferred energy source, but its ability to utilize L-fucose can grant a competitive ...
