The properties of seven enzymes were studied in extracts from Myxobacter AL-1. The enzymes were isocitrate dehydrogenase (E.C.1.1.1.42), succinate dehydrogenase (E.C.1.3.99.1), alkaline phosphatase (E.C.3.1.3.1), alpha-glucosidase (E.C.3.2.1.20), beta-glucosidase (E.C.3.2.1.21), beta-galactosidase (E.C.3.2.1.23), and N-acetyl-glucosaminidase (E.C. 3.2.1.30). Four of these enzymes: isocitrate dehydrogenase, alpha-glucosidase, beta-glucosidase, and beta-galactosidase are cytosolic enzymes. Succinate dehydrogenase was found to be located on the cytoplasmic membrane system, whereas alkaline phosphatase and N-acetylglucosaminidase were considered as enzymes which bind the outer membranes resp. the cell wall. During the cell cycle, all enzymes have a pattern of discontinuous activity increase. Succinate dehydrogenase and isocitrate dehydrogenase exhibit a stepwise increase of activity, whereas the other enzymes follow the pattern of a peak enzyme.
对粘细菌AL-1提取物中的七种酶的特性进行了研究。这些酶分别是异柠檬酸脱氢酶（E.C.1.1.1.42）、琥珀酸脱氢酶（E.C.1.3.99.1）、碱性磷酸酶（E.C.3.1.3.1）、α-葡萄糖苷酶（E.C.3.2.1.20）、β-葡萄糖苷酶（E.C.3.2.1.21）、β-半乳糖苷酶（E.C.3.2.1.23）和N-乙酰葡糖胺酶（E.C. 3.2.1.30）。其中四种酶：异柠檬酸脱氢酶、α-葡萄糖苷酶、β-葡萄糖苷酶和β-半乳糖苷酶是胞质酶。发现琥珀酸脱氢酶位于细胞质膜系统上，而碱性磷酸酶和N-乙酰葡糖胺酶被认为是分别结合外膜和细胞壁的酶。在细胞周期中，所有酶都有活性增加不连续的模式。琥珀酸脱氢酶和异柠檬酸脱氢酶的活性呈逐步增加，而其他酶则呈现出酶活性峰值的模式。
