- cyclohexylsulfamate metabolic process
The chemical reactions and pathways involving cyclohexylsulfamate, also known as cyclamic acid. Sodium cyclohexylsulfamate (CHS-Na) was a widely used sweetening agent but was banned because of the suspicion of carcinogenicity and metabolic conversion to cyclohexylamine (CHA), a toxic substance. It is now used as a fungicide.
- ribonucleotide excision repair
The pathway by which a ribonucleotide is removed from DNA and replaced by a deoxyribonucleotide. The ribonucleotide is incised by RNase H2, and further excised by an endonuclease. The resulting 1 nt gap is then repaired by DNA polymerase and DNA ligase.
- energy quenching
The process by which excess light energy absorbed by chlorophyll and not used to drive photosynthesis is emitted by nonphotochemical quenching or chlorophyll fluorescence.
