The actin cytoskeleton plays incredibly important roles in our cells.

肌动蛋白骨架在我们的细胞中扮演着至关重要的角色。

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

和我们的骨架不同，肌动蛋白纤维（微丝） 一直在不停的被组装和拆散。

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

具体说，棒状头肌球蛋白想近距离接触肌动蛋白。

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

在我们的肌肉细胞中，肌动蛋白结形成了这些看起像布料的规则纤维。

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

无法靠呼吸脱氧核糖核酸、肌动蛋白或磷脂双分子层所需的东西。

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

它们有自己著名的联结——一对漂亮的微小蛋白质链，叫做肌动蛋白和肌球蛋白。

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

就像我们肌肉中的肌动蛋白和肌球蛋白一样，它们使我们能够移动。

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

好像很快乐 斯佳丽。

Soap? Deodorant? The toughest actin' Tinactin?

肥皂? 除臭剂? 还药效最强的牛皮癣喷雾?

Why? Why was she actin' out?

为什么 为什么她要出走？

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

看到那些好玩的黑眼睛的村民回游荡看上去像疯了一样?

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

它的动作由我最喜欢的蛋白之一，肌动蛋白驱动，这种蛋白所谓 “细胞骨架”的一部分。

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的了。

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

也就说，肌动蛋白会被蛋白质的保镖阻断——原肌球蛋白和肌钙蛋白——它们一直碍事。

" 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，我看得出们有很多事要做，”苏珊·索尔比说。

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的部分，其中包含两股更小的蛋白质——两种不同的肌丝称为肌动蛋白和肌球蛋白。

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的肌动蛋白链组成，也包含粗丝，由更厚、看起块状的肌球蛋白链组成。

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

当玛莎议我“稍微注意一下亨利的行为方式” 时，我认为参孙和他的威严让他感到厌烦。

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，当肌球蛋白准备好行动，保镖离开，肌球蛋白最终与肌动蛋白结合，这真太美了。

If another action potential travels down before that can happen, even more calcium gets released, which ends up exposing more actin for myosin to bind to, and that means more force in that fiber.

如果另一个动作电位在此之前下降，更多的钙被释放出，最终暴露出更多的肌动蛋白结合肌球蛋白，这意味着纤维中有更多的力量。
