Article Synopsis
  • - Zearalenone (ZEN) is a harmful fungal toxin linked to reproductive issues in both animals and humans, and its removal is crucial for health and safety.
  • - Current methods using ZEN lactonases struggle with thermal stability, but a new engineered enzyme variant, I160Y-G242S, shows about 40% activity retention at 55℃ after 10 minutes, making it the most heat-tolerant ZEN hydrolase reported.
  • - The I160Y-G242S variant also exhibits twice the effectiveness compared to its predecessor, thanks to enhanced stability and improved interactions with its substrate, making it a promising option for ZEN degradation in industrial applications.

Hypothetical proteins (HPs) are non-predicted sequences that are identified only by open reading frames in sequenced genomes, but their protein products remain uncharacterized by any experimental means. The genome of every species consists of HPs that are involved in various cellular processes and signaling pathways. Annotation of HPs is important as they play a key role in disease mechanisms, drug designing, vaccine production, antibiotic production, and host adaptation.

Background: Since the SARS-CoV-2 outbreak in December 2019 in Wuhan, China, the virus has infected more than 153 million individuals across the world due to its human-to-human transmission. The USA is the most affected country having more than 32-million cases till date. Sudden high fever, pneumonia and organ failure have been observed in infected individuals.

HPPD gene codes a dioxygenase enzyme involved in catalysis of different molecules such as tyrosine and phenylalanine by oxidizing them to produce energy. A single change in protein can trigger serious genetic disorders like Tyrosinemia type III and Hawkinsinuria. This study aims to identify the functional missense SNPs of the HPPD gene by using multiple computational tools.

Primary microcephaly (MCPH) is an autosomal recessive sporadic neurodevelopmental ailment with a trivial head size characteristic that is below 3-4 standard deviations. MCPH is the smaller upshot of an architecturally normal brain; a significant decrease in size is seen in the cerebral cortex. At birth MCPH presents with non-progressive mental retardation, while secondary microcephaly (onset after birth) presents with and without other syndromic features.

Objective: Human adenoviruses are small double stranded DNA viruses that provoke vast array of human diseases. Next generation sequencing techniques increase genomic data of HAdV rapidly, which increase their serotypes. The complete genome sequence of human adenovirus shows that it contains large amount of proteins with unknown cellular or biochemical function, known as hypothetical proteins.
