Polypeptide Substrate Specificity of PsLSMT

Polypeptide substrate specificity of PsLSMT. A set domain protein methyltransferase.

Rubisco large subunit methyltransferase (PsLSMT) is a SET domain protein responsible for the trimethylation of Lys-14 in the large subunit of Rubisco. The polypeptide substrate specificity determinants for pea Rubisco large subunit methyltransferase were investigated using a fusion protein construct between the first 23 amino acids from the large subunit of Rubisco and human carbonic anhydrase ...

Substrate Specificity of MMPs

The substrate specificity of fumarase.

The substrate specificity of fumarase has been studied by measuring the ability of the enzyme to hydrate or dehydrate derivatives of fumarate and L-malate. Fumarase was observed to hydrate fumarate and its derivatives in the order, fluorofumarate > fumarate > chlorofumarate > bromofumarate > acetylenedicarboxylate > iodofumarate > mesaconate. With the exception of fluorofumarate, water was adde...

2 Substrate Specificity of MMPs

Substrate specificity of soybean lipoxidase.

Purified soybean lipoxidase was used to test the substrate specificity of all cis,ck-methylene-interrupted isomers of linoleic acid. The natural 9, U-isomer was found to be the best substrate, and the 13,16-isomer 50% as effective. The presence of calcium ions broadened the pattern of specificity. The rates of reaction of a series of polyunsaturated acids in which chain length, number of double...
