31. The other is known as 3-methyl histidine , a structural component of muscle. 32. Histidine kinases are also found in plants, fungi, animals, and other eukaryotes.33. In the Histidine variant, the enzyme is much more effective at the aforementioned conversion. 34. The mutation causes substitution of codon 206 from arginine to histidine in the ACVR1 protein. 35. The cluster is linked to the protein by the amino acid residues cysteine and histidine . 36. The biosynthesis of histamine from histidine is catalyzed by the enzyme L-histidine decarboxylase. 37. The biosynthesis of histamine from histidine is catalyzed by the enzyme L-histidine decarboxylase. 38. It is primarily used as a dehydrogenase by causing the methoxycarbonylation of their histidine components. 39. Signal transducing histidine kinases are the key elements in two-component signal transduction systems. 40. The amino acid histidine , when catalyzed by the enzyme histidase, forms urocanic acid.
