Cystinosis, Ocular NonnephropathicHomo sapiens
Ocular non-nephropathic cystinosis, also known as adult-onset cystinosis, is a rare inborn error of metabolism (IEM) and autosomal recessive disorder of the cysteine metabolism pathway. It is caused by a defect in the CTNS gene, which encodes the protein cystinosin, which acts as a cystine/H+ symporter that transports L-cysteine out of the lysosome. Ocular non-nephropathic cystinosis is characterized by a buildup of cysteine in cells, in the case of this form in the cornea. Symptoms include photophobia and damage to the cornea due to crystals forming from the excess cysteine. However, unlike other forms of cystinosis, no or minimal kidney damage occurs. Treatment with cysteamine, a drug that can convert cysteine into a form that can be secreted by the lysosome, can be effective in all of the forms of cystinosis. It is estimated that ocular non-nephropathic cystinosis affects less than 1 in 100,000 to 200,000 individuals, which is the rate of the more severe nephropathic cystinosis.

CystinuriaRattus norvegicus
Cystinuria is a genetic condition caused by mutations in the SLC7A9 or SLC3A1 gene. These two genes are responsible for creating subunits of a protein that reabsorbs cystine into the blood, located in the kidneys. The mutations cause this process to be compromised and allows the amino acids to build up and have a high concentration in urine. This causes crystals to form and become stones as they grow larger. These stones can become lodged in the bladder or in the kidneys which can cause pain, develop infection and disrupt the passing of urine through the urinary tract if the stones create a blockage there.

Cytokinins DegradationArabidopsis thaliana
Cytokinins (CK) are a class of plant growth substances (phytohormones) that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence. . Their regulation can take the form of biosynthesis, import, conjugation, and degradation. Homeostasis regulation by irreversible degradation is carried out by cytokinin oxidases which form adenine-like compounds resulting from the cleavage of the N6-isopentenyl-side chain. The cytokinins degradation pathway consists of five different degradation reactions that can be localized to either the endoplasmic reticulum or the vacuole. Cytokinin oxidase was found to catalyze two such reactions: the conversion of N6-dimethylallyladenine into 3-methyl-2-butenal and adenine and the conversion of trans-zeatin into 3-methyl-4-trans-hydroxy-2-butenal and adenine. It has not yet been determined if cytokinin oxidase also catalyzes the other three reactions in the cytokinins degradation pathway: the conversion of isopentenyl adenosine into adenosine and 3-methyl-2-butenal, the conversion of cis-zeatin into 3-methyl-4-cis-hydroxy-2-butenal and adenine, and the conversion of trans-zeatin riboside into 3-methyl-4-trans-hydroxy-2-butenal and adenosine. As such, the enzyme of these reactions are coloured orange in the image.
