The actin cytoskeleton plays incredibly important roles in our cells.

肌动白骨架在我们细胞中扮演着至关重要。

Actin is also involved in a different kind of movement.

肌动白还和另一种不同运动有关。

Unlike our skeletons, actin filaments are constantly being built and taken apart.

和我们骨架不同，肌动白纤维（微丝） 一直在不停被组装和拆散。

Specifically, that club-headed myosin wants to get all up-close-and-personal with the actin.

具体来说，棒状头肌球白想近距离接触肌动白。

In our muscle cells, actin structures form these regular filaments that look kind of like fabric.

在我们肌肉细胞中，肌动白结构形成了这些看起来像布料规则纤维。

Like the actin and myosin in our muscles that enable us to move.

就像我们肌肉中肌动白和肌球白一样，它们使我们能够移动。

You actin' mighty happy this mornin', Miss Scarlett.

你好像很快乐 斯佳丽。

Soap? Deodorant? The toughest actin' Tinactin?

肥皂? 除臭剂? 还是药效最强牛皮癣喷雾?

Why? Why was she actin' out?

为什么 为什么她要出走？

This movement is powered by one of my favorite proteins called actin, which is part of what's known as the cytoskeleton.

它动作由我最喜欢白之一，肌动白驱动，这种白是所谓 “细胞骨架”一部分。

See those funny big black-eyes folks we were runnin' around with actin' all crazy?

看到那些好玩黑眼睛村民来回游荡看上去像疯了一样?

They've got their own famous coupling — a pretty pair of tiny protein strands called actin and myosin.

它们有自己著名联结——一对漂亮微小白质链，叫做肌动白和肌球白。

They'll get a good bit o' actin' out of it an' there's nothin' children likes as much as play actin'.

他们会从中得到一些表演，没有什么比表演更让孩子们喜欢了。

" Bless us all, I can see tha' has a good bit o' play actin' to do, " said Susan Sowerby.

“保佑我们所有人，我看得出来你们有很多事要做，”苏珊·索尔比说。

Namely, actin is blocked by a couple of protein bodyguards — called tropomyosin and troponin — which keep getting in the way.

也就是说，肌动白会被白质保镖阻断——原肌球白和肌钙白——它们一直碍事。

But you can't just breathe in the stuff you need to build DNA, or actin, or a phospholipid bilayer.

但是你无法仅仅靠呼吸来构建脱氧核糖核酸、肌动白或磷脂双分子层所需东西。

They're divided lengthwise into segments called sarcomeres, which contain two even tinier strands of protein — two different kinds of myofilaments called actin and myosin.

它们在纵向上被分成称为肌节部分，其中包含两股更小白质——两种不同肌丝称为肌动白和肌球白。

A sarcomere contains both thin filaments, made up mostly of two light and twisty actin strands, and thick filaments, composed of thicker, lumpy-looking myosin strands.

肌节既包含细丝，主要由两条轻盈而扭曲肌动白链组成，也包含粗丝，由更厚、看起来块状肌球白链组成。

When Martha suggested to me that I " kind o' notice the way Henry's actin', " I decided that Samson and his lordliness irked him.

当玛莎建议我“稍微注意一下亨利行为方式” 时，我认为参孙和他威严让他感到厌烦。

So after all that, with the myosin primed for action and the bodyguards out of the way, the myosin finally binds to actin, and it is beautiful.

经过这一切，当肌球白准备好行动，保镖离开，肌球白最终与肌动白结合，这真是太美了。
