Yybt and Me
Yybt is a un-characterised Bacillus sub. bacterial protein that I have been working on for the past 2 months, its exact function is unknown, but research so far has indicate that it is involved in a novel signalling pathway, particularly unique to firmicutes (gram positive bacteria). Even more interesting, it is postulated to function as a stress sensor or for in vivo survival!! Recent discovery has associate this protein to invivo pathogenesis in medically important bacteria, such as Clostridium and Stapylococcus aures!! That is why elucidating the invivo function and understanding this protein might eventually lead to a greater understanding of bacteria signalling and even pathogenesis of medically important pathogens for novel drug targets.
We learn in biochemistry that by targeting proteins that are essential for invivo function, we can significantly reduce selective pressure for antibiotic resistance and do not disrupt normal flora composition that may lead to superinfection. That is why me n my mentor Rao Feng is so excited about researching on Yybt and its homologs, it is indeed an exciting and new area to venture into.
I use to thought biochemistry was just about kinetics and mechanism, but i was so wrong. During my 2 month research, not only did i touch alot of kinetics, i was also involved in trying to probe the invivo function. This includes classic microbiology work like acid challenge, biofilm formation. Its sad not to be able to comprehend the beauty of the 3D structure, as I haven attempt some yr 3 modules such as structural n computational biology.
Hui Jie and Qing Ting was involved in PKS, another very interesting mega-synthetase, invovle in antibiotics synthesis! They are very well trained in protein expession, purification, and protein n DNA gel, it will definately prove useful to have such skills, as protein expression is essential for most labs. Has been fun to share and come up with weird mechanism and hypothesis with huijie, thanks huijie for sharing my woos, sometime i might seem frastrated, but i never meant it.
Me experience there has been nothing but inspiring, though there was alot of dissapointment at time, but its all part of research. Lawerence table had this qoute that sound somthing like "we fear what is the unknown, therefore we seek desperately for knowledge to overcome our fear" truely inspiring. I respect all the researcher in pursing to discover the truth behind the unknown. Rao Feng is a great mentor and researcher, his hypothesis and ideas comes so fast, its amazing just to keep up in pace with him, let alone anticipate what is the next experiment to be done. I can only say he is truely inspiring. I felt really reluctant to leave the research, yet yearning to take a break. Research is exciting, intriguing but its very taxing, this experience was really inspiring, and really make me wanna be one of them someday.
For memories sake, shall upload some of the lab foto, his place can be considered the most cluttered, he ask me not to learn from him in this aspect, but if it works for him, why not?
racks of reagent all around, with HPLC vial cap all over the place
to do work, have to push everything behind, no space.
many many falcon tubes of reagent, you want what its all there from buffer to distill water, from loading dye to MgCl2.
I will miss that place, abit gay, and Rao Feng also. On the last day, he asked if when is my FYP, i told him 1.5 yrs later and most prob he is not around anymore, he joke and say he better not be around, or else someting is terribly wrong with his phd. So long Yybt, i will miss ur DHH domain- phophodiesterase activity, PAS domain- heme association, DDGEF domain- ATPase activity, ppGpp, pGpG, pApA, CDG, CDA, ATP, GTP, AMPNPP, RocR. I have to move on, hopefully, nxt time when i see you i would know you better. Thanks Rao Feng, for the guidance and patience with me.
