11-beta-Hydroxylase Deficiency (CYP11B1)

Mus musculus
11-beta-Hydroxylase Deficiency, also called congenital adrenal hyperplasia (CAH), is an autosomal recessive disorder and caused by a defective 11-beta-hydroxylase. 11-beta-hydroxylase catalyzes the conversion of cortexolone into cortisol which is useful for maintaining blood sugar levels and suppressing inflammation. This disorder is characterized by a large accumulation of cortexolone in the endoplasmic reticulum (ER). Symptoms of the disorder include abnormality of hair growth rate and menstrual cycle. It is estimated that 11-beta-hydroxylase deficiency affects 1 in 100,000 to 200,000 newborns.

1-Methylhistidine Metabolism

Homo sapiens
Methylhistidine is a modified amino acid that is produced in myocytes during the methylation of actin and myosin. It is also formed from the methylation of L-histidine, which takes the methyl group from S-adenosylmethionine and forms S-adenosylhomocysteine as a byproduct. After its formation in the myocytes, methylhistidine enters the blood stream and travels to the kidneys, where it is excreted in the urine. Methylhistidine is present in the blood and urine in higher concentrations after skeletal muscle protein breakdown, which can occur due to disease or injury. Because of this, it can be used to judge how much muscle breakdown is occurring. Methylhistidine levels are also affected by diet, and may differ between vegetarian diets and those containing meats.

1,6-Anhydro-N-acetylmuramic Acid Recycling

Escherichia coli
Most bacteria, including Escherichia coli, are composed of murein which protects and stabilizes the cell wall. Over half of the murein is broken down by Escherichia coli and recycled for the next generation. The main muropeptide is GlcNAc-anhydro-N-acetylmuramic acid (anhMurNAc)-l-Ala-γ-d-Glu-meso-Dap-d-Ala which enters the cytoplasm by AmpG protein. The peptide is then released from the muropeptide. 1,6-Anhydro-N-acetylmuramic acid (anhMurNAc) is recycled by its conversion to N-acetylglucosamine-phosphate (GlcNAc-P). The sugar is phosphorylated by anhydro-N-acetylmuramic acid kinase (AnmK) to produce MurNAc-P. Etherase cleaves MurNAc-P to produce N-acetyl-D-glucosamine 6-phosphate. The product can undergo further degradation or be recycled into peptidoglycan monomers. The pathway's final product is a peptidoglycan biosynthesis precursor, UDP-N-acetyl-α-D-muramate. The enzyme muropeptide ligase (mpl), attaches the recovered Ala-Glu-DAP tripeptide to the precursor UDP-N-acetyl-α-D-muramate to return to the peptide to the peptidoglycan biosynthetic pathway to synthesize the cell wall.
