New Enzyme To Arrest Bacterial Growth Discovered By CCMB Scientists

Center for Cellular & Molecular Biology (CCMB) Scientists has found a new enzyme which helps in breaking cell walls of bacteria and consequently, offers a potential for a new drug delivery route to arrest the anti-bacterial resistance through existing antibiotic drugs.

In a press conference held on Tuesday, CCMB Director Rakesh Mishra and Seniors scientist Manjula Reddy explained – that for research it is vital to understand how the cells grow in bacteria to comprehend the resistance to antibiotics that were currently available.

Scientists all around the world are trying to understand this phenomenon. Dr. Reddy Labs has been analyzing the way e.coli bacteria cells operate, split and grow to understand diseases like cholera, leprosy, tuberculosis and so on.

Dr. Reddy along with her research scholar Ch. Pavan Kumar has been working on how the cell governs the machinery to construct the cell wall in the first place, identified the players on the other side of the process and discovered that the mechanism or enzyme through which the cell regulates the growth of its wall.

Other bacteria, also, have the enzyme since the cell wall is fundamental for bacterial growth and division. By blocking this ‘scissors’ enzyme’ from working – effective ways to target microbes can be figured out leading to the development of novel antibiotics.

In contrast, existing antibiotic drugs functions by targeting the last stages in cell development to block cell growth like penicillin that hits on the machinery that creates the cell wall – a mesh-like structure of sugars and peptides.

Dr. Mishra and Dr. Reddy Concluded that – The Research done till now is very innovative. Now further they have to find out the molecule of the enzyme endo-pepcidine and it needs to undergo drug trials to unravel a new mix of drugs to replace existing antibiotics though it’s tough to forecast a timeframe.

The above research by CCMB can be read at the latest issue of Proceedings of National Academy of Sciences, USA.

Beer production

Brewing is the production of beer by steeping a starch source (commonly cereal grains, the most popular of which is barley ) [1] in water and fermenting the resulting sweet liquid with yeast . It may be done in a brewery by a commercial brewer, at home by a homebrewer , or by a variety of traditional methods such as communally by the indigenous peoples in Brazil when making cauim . [2] Brewing has taken place since around the 6th millennium BC, and archaeological evidence suggests that emerging civilizations including ancient Egypt [3] and Mesopotamia brewed beer. [4] Since the nineteenth century the brewing industry has been part of most western economies. The basic ingredients of beer are water and a fermentable starch source such as malted barley . Most beer is fermented with a brewer's yeast and fl...

What is Insomnia? If you can't sleep, you may be wondering if you have insomnia. Insomnia is a complicated condition. What is the definition of insomnia? According to guidelines from a physician group, insomnia is difficulty falling asleep or staying asleep, even when a person has the chance to do so. People with insomnia can feel dissatisfied with their sleep and usually experience one or more of the following symptoms : fatigue, low energy, difficulty concentrating, mood disturbances, and decreased performance in work or at school. How long does insomnia last? Insomnia may be characterized based on its duration. Acute insomnia is brief and often happens because of life circumstances (for example, when you can't fall asleep the night before an exam, or after receiving stressful or bad news). Many people may have experienced this type of passing sleep disruption, and it tends to resolve without any treatment. Chronic insomnia is d...

Ethanol fermentation

Ethanol fermentation Read in another language Watch this page Edit In ethanol fermentation, (1) one glucose molecule breaks down into two pyruvates. The energy from this exothermic reaction is used to bind the inorganic phosphates to ADP and convert NAD+ to NADH. (2) The two pyruvates are then broken down into two acetaldehydes and give off two CO2 as a by-product. (3) The two acetaldehydes are then converted to two ethanol by using the H- ions from NADH, converting NADH back intoNAD+. Ethanol fermentation , also called alcoholic fermentation , is a biological process which converts sugars such as glucose , fructose , and sucrose into cellular energy , producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen , alcoholic fermentation is conside...
