Identification and characterization of BAHD hydroxycinnamoyltransferases in the fern Neoblechnum brasiliense. [PDF]
Significance Statement Nine BAHD acyltransferases have been identified and characterized in the fern Neoblechnum brasiliense transferring hydroxycinnamoyl units onto various alcohol and amine acceptor substrates. Kinetic characterization showed that shikimic and quinic acids for ester formation as well as 3‐hydroxyanthranilic acid and tryptamine for ...

Molecular Analysis of the HGD Gene in 9 Families With Alkaptonuric Ochronosis in Iran and Identification of Two Novel Variants. [PDF]
There has been a wide range of mutations identified in the HGD gene in alkaptonuric patients. Some HGD mutations are spread worldwide, while others are specific to certain countries. Alkaptonuria has not been extensively studied in Iran; it is likely to be high since consanguineous marriages are common.

Alkaptonuric ochronosis of the carotid artery
Alkaptonuria is a rare autosomal-recessive metabolic disorder of tyrosine degradation which results in elevated levels of circulating homogentisic acid. Ochronosis occurs when homogentisic acid polymerizes and deposits in connective tissue.

Detection of novel visible-light region absorbance peaks in the urine after alkalization in patients with alkaptonuria. [PDF]
BACKGROUND: Alkaptonuria, caused by a deficiency of homogentisate 1,2-dioxygenase, results in the accumulation of homogentisic acid (2,5-dihydroxyphenylacetic acid, HGA) in the urine.

Tocopherol and plastoquinone synthesis in spinach chloroplasts subfractions [PDF]
Subfractions isolated from intact purified spinach chloroplasts are able to prenylate the aromatic moiety of -tocopherol and plastoquinone-9 precursors. The biosynthesis of -tocopherol and plastoquinone-9 is a compartmentalized process.
