Abstract

The synthesis of chlorophyll a and the bile-pigment and protein moieties of phycocyanin were arrested in illuminated cells of Cyanidium caldarium, strain III-D-2, incubated with chloramphenicol, ethionine, p-fluorophenylalanine, and p-chloromercuribenzoate. Pigment synthesis was similarly retarded in illuminated cells provided with nutrient medium lacking nitrogen.Porphobilinogen, porphyrins, and a blue phycobilin were excreted into the nutrient medium by illuminated and unilluminated cells of wild-type and mutant C. caldarium strains incubated with delta-aminolevulinic acid in darkness. Pigment production from delta-aminolevulinic acid was sensitive to treatment with chloramphenicol and ethionine. Cells of C. caldarium excreted 7 red-fluorescing porphyrins into the suspending medium during incubation with delta-aminolevulinic acid. Three of these porphyrins were identified as uroporphyrin III, coproporphyrin III, and protoporphyrin on the basis of their spectral properties and by paper chromatogaphy with standards. The blue phycobilin was characterized spectrally and compared with biliverdin. The algal phycobilin displayed properties of a pigment with a violin-type structure. The phycobilin may be an immediate precursor of phy...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Enzyme Evolution

This feed focuses on molecular models of enzyme evolution and new approaches (such as adaptive laboratory evolution) to metabolic engineering of microorganisms. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pharmacology of Proteinopathies

This feed focuses on the pharmacology of proteinopathies - diseases in which proteins abnormally aggregate (i.e. Alzheimer’s, Parkinson’s, etc.). Discover the latest research in this field with this feed.

Alignment-free Sequence Analysis Tools

Alignment-free sequence analyses have been applied to problems ranging from whole-genome phylogeny to the classification of protein families, identification of horizontally transferred genes, and detection of recombined sequences. Here is the latest research.
