英文名称: AP-M; LAP; Leucine Aminopeptidase, microsomal from porcine kidney; α-Aminoacyl-Peptide Hydrolase (microsomal) ;Amino Acid Arylamidase; Aminopeptidase M 其他名称: 亮氨酸氨肽酶; 肽链外切酶; 白氨酸氨肽酶; 氨基肽酶M CAS号: 9054-63-1 级别: BR 活力: 10~40 units/ mg protein (Bradford) 活力定义: One unit will hydrolyze 1.0 μmole of L-leucine-p-nitroanilide to L-leucine and p-nitroaniline per min at pH 7.2 at 37 °C. (At 25 °C, approx. 40% of the activity at 37 °C is obtained.) The activity obtained using L-leucine p-nitroanilide as substrate is 2-5 times that obtained with L-leucinamide as substrate 性状: 悬浮液.Suspension in 3.5 M (NH4) 42SO4 solution, pH 7.7, containing 10 mM MgCl2. 是尿酶的组成成分之一, 为细胞内溶酶体水解酶, 广泛分布于肾, 肝, 结缔组织, 唾液腺, 淋巴结等组织中. 分子量约255000 保存: 2~8℃ |
