Preterm-metabolite paper published

I am pleased to report the publication of a joint paper between ourselves- Emmanuel Amabebe and Jen Parker and lead by Dilly Anumba on the work conducted on the preterm birth project assessing metabolite levels by NMR.  The NMR  work was lead by Steve Reynolds with Martyn Paley and shows some interesting findings suggesting selected metabolites detectable in the GU tract of pregnant women have the potential to help the diagnostic process indicating increased risk of Premature birth.

Sialic acid-tastic in 2015

We are pleased to announce that two of our papers with valued collaborators on two aspects of sialic acid biology in Tannerella were published in autumn 2015.

Phansopa et al, describes characterisation of a novel SGNH hydrolase that cleaves acetyl-groups from di-acetylated sialic acids (Neu5,9 and Neu5,4) to allow access of sialidases.  This was a collaborative effort with the team from Ludger Ltd and should precede other big news on this collaboration.

Honma et al., describes the import of NanT sialic acid transporter in sialic acid uptake and intracellular survival in human cells and is the latest in a line of papers with Ashu Sharma from SUNY-at Buffalo.


Phansopa C, Kozak RP, Liew LP, Frey AM, Farmilo T, Parker JL, Kelly DJ, Emery RJ, Thomson RL, Royle L, Gardner RA, Spencer DI, Stafford GP (2015) Characterization of a sialate O-acetyl esterase (NanS) from the oral pathogen Tannerella forsythia that enhances sialic acid release by NanH its cognate sialidase. Biochem J. 2015 Sep 16. pii: BJ20150388

Honma K, Ruscitto A, Frey AM, Stafford GP, Sharma A. (2015) Sialic acid transporter NanT participates in Tannerella forsythia biofilm formation and survival on epithelial cells. Microb Pathog. 2015 Aug 28. pii: S0882-4010(15)00143-6. doi: 10.1016/j.micpath.2015.08.012.  

Congratulations Charlotte Green- Queen of ABC posters

Many congratulations to Charlotte Green whose poster on Re-engineering of the Bacterial flagellum for high efficiency secretion won the MedImmune sponsored poster prize at the inaugural Advanced Biomanufacturing Centre (ABC) meeting in Sheffield May 18-19th 2015.  She was commended on a clear visual poster- which you can see here with her certificate and poster looking very chuffed!  Well done Charlotte.

Graham also spoke at the meeting on our work on bacterial glycosidases and their potential in glycoanalytic pathways.

Well done to Karen Wood on organising a great meeting.

Zoe Megsons Fucosidase paper published

We are happy to see Zoe Megsons fucosidase paper published in virulence journal this week.  Not only is it our first paper with the group of Tina Schaeffer at BOKU, Vienna, it also characterises a novel GH29 enzyme from Tannerella that Zoe studied. Some of the work was conducted in Sheffield on her visit here last summer while we also supplied rNanH to complement her work.

Kate wins OMIG poster prize in Amsterdam, Feb 2015

Congratulations to Kate Naylor, whose talk at the Oral Microbiology and Immunology Group

Postgraduate Prize meeting at ACTA in Amsterdam in February this year won the runner up prize from a strong field of 15 talks.

We were all amazed by the space-age facilities at ACTA, and look forward to similar upgrades in Sheffield!!

Congratulations also to Mohammed Zubidi for giving his first talk on oral prophage at an oral microbiology meeting while Andy also gave a talk on his work with sialidases.

Rebecca Lowry's Aeromonas paper published

Congratulations to Rebecca on the publication of her paper on Aeromonas cell length determination by the cryptic AHA_0618 gene.  This paper was a labour of love for all involved and showcases a real tangible amount of sweat all around.  The gene was previously thought to be involved in glycosylation of flagellin in Aeromonas, a hypothesis that this work disproves while also indicating that it may modify cell wall composition and this influence cell length.
