Protocollagen Proline Hydroxylase from Ascaris lumbricoides

Protocollagen proline hydroxylase from Ascaris lumbricoides.

An enzyme was found in the muscle layers of Ascaris lumbricoides which was similar to the protocollagen proline hydroxylase found in chick embryos and other vertebrates in that it synthesized 14C-hydroxyprolme when incubated with 14C-proline-labeled protocollagen from chick cartilage. The Ascaris enzyme was also similar in that it required atmospheric oxygen, a-ketoglutarate, iron, and ascorbat...

Denatured collagen from the cuticle of Ascaris lumbricoides as a substrate for protocollagen proline hydroxylase.

Recent studies have shown that the hydroxyproline and hydroxylysine found in the collagen of vertebrates are synthesized by the hydroxylation of proline and lysine, which have been incorporated into a large polypeptide precursor of collagen called protocollagen. Because the collagen isolated from the cuticle of Ascaris lumbricoides contains less hydroxyproline and hydroxylysine than any other k...

Ascaris Lumbricoides

Ascaris lumbricoides--the ubiquitous roundworm.

Ascaris lumbricoides: a case report.

This is a case presentation of a multiple trauma patient who was infested with Ascaris lumbricoides, a roundworm. The infestation was undiagnosed until after extubation. Intraoperative anesthesia was uneventful and the patient was discharged 7 days after admission.
