Both the macrobenthos density and the number of species were found to be higher in the outer shelf region where the sediment contained high bioavail able protein. 大型底棲動(dòng)物之密度及種類(lèi)豐富度以陸棚外側之可利用蛋白質(zhì)含量的地區最高。
Protein engineering and site directed mutagenesis have been used to change the active site and alter the substrate specificity of various hydroxynitrile lyases. 研究人員已經(jīng)利用蛋白質(zhì)工程和定點(diǎn)突變技術(shù)來(lái)改變各種醇腈酶的活性位點(diǎn)和底物特異性等。
